Medical Surgical Exam 4 (NSG 123)

The correct answer is D: back rather than on the stomach

Explanation for the correct answer:

D. back rather than on the stomach

The back-to-sleep position is the recommended and safest sleep position for infants to prevent sudden infant death syndrome (SIDS). Research has shown that placing infants on their backs for sleep significantly reduces the risk of SIDS. This practice has been strongly endorsed by organizations like the American Academy of Pediatrics (AAP).

Why the other options are incorrect:

A. side or prone

Placing an infant in the side position is not recommended because it is not as safe as the back position and may increase the risk of the infant rolling onto their stomach. The prone (stomach) position is a known risk factor for SIDS, as it can lead to suffocation or overheating.

B. back or prone

While the back position is correct, the prone position is not. This option includes the prone position, which is dangerous and increases the risk of SIDS.

C. stomach with the face turned

Placing the infant on their stomach even with the face turned is dangerous and should be avoided. This position increases the risk of suffocation and is strongly discouraged by health organizations to reduce the risk of SIDS.

Summary:

The safest sleep position for an infant is to place them on their back, as this has been shown to significantly reduce the risk of SIDS. The prone (stomach) and side positions should be avoided.

The correct answer is:

A. permit visitors to stay with client for 30 min at a time

B. warn pregnant individuals to visit room only once daily

C. wear dosimeter when in client's room

Explanation for the correct answer:

A. permit visitors to stay with client for 30 min at a time

For a client undergoing brachytherapy, which involves the use of radioactive materials implanted inside or near the tumor, precautions need to be taken to limit exposure to radiation. Visitors should be limited to a certain time frame (e.g., 30 minutes) to minimize their exposure to radiation. Limiting the time visitors spend in the room reduces the risk of radiation exposure.

B. warn pregnant individuals to visit room only once daily

Pregnant individuals should be especially cautious around clients receiving brachytherapy due to the potential harm radiation can cause to a developing fetus. It is recommended that pregnant individuals visit the room only once daily to minimize their exposure to radiation.

C. wear dosimeter when in client's room

A dosimeter is a device used to measure radiation exposure. Nurses and healthcare workers caring for patients receiving brachytherapy should wear dosimeters to monitor the amount of radiation they are exposed to while in the room. This is essential for ensuring that healthcare providers are not exposed to unsafe levels of radiation.

Why the other options are wrong:

D. place soiled dressings in biohazard bag before discarding in regular trash

This is incorrect. Soiled dressings should be placed in a specific container for radioactive waste, not in a regular biohazard bag. Brachytherapy involves radioactive materials, and special handling for items contaminated with radioactive substances is required. These materials should be discarded in designated radioactive waste containers to prevent unnecessary exposure to radiation.

E. dispose soiled linens in the hamper outside client's room

This is incorrect. Soiled linens from a patient receiving brachytherapy should not be disposed of in the general laundry hamper. These linens should be handled as radioactive waste and disposed of according to the hospital’s radiation safety protocols. Linen that has been contaminated with radioactive material must be properly contained and disposed of to prevent the spread of radiation.

Summary:

When caring for a client undergoing brachytherapy, it is important to limit visitor time to reduce radiation exposure (A), advise pregnant individuals to visit only once daily (B), and wear a dosimeter to monitor radiation exposure (C). Soiled dressings and linens must be handled according to radiation safety protocols, and regular trash or general biohazard disposal should be avoided.

The correct answer is A: Cancer does not make you sterile, but sometimes the therapy can

Explanation for the correct answer:

A. Cancer does not make you sterile, but sometimes the therapy can.

This response is the most accurate and informative for the client. It acknowledges that while bladder cancer itself does not cause sterility, treatments such as surgery, chemotherapy, or radiation may affect fertility. This answer provides the client with factual information about fertility and encourages further discussion about the impact of cancer treatment on reproductive health, allowing for the exploration of options if desired.

Why the other options are wrong:

B. Are you concerned you can't have children?

While this question might seem empathetic, it places the focus on the nurse's perception of the client’s feelings, rather than providing factual information. It's more helpful to address the client's concern directly and provide the information they are seeking, as option A does. This response also lacks the necessary information about how cancer treatments can affect fertility.

C. You will be able to have as many children as you want.

This statement is overly optimistic and misleading. It assumes that fertility will not be affected by the cancer treatment, which is not necessarily true. By stating this, the nurse may inadvertently provide false hope and fail to address the potential effects of cancer treatment on the client’s ability to conceive.

D. Let me have the chaplain come to talk with you about this.

While involving a chaplain may be beneficial for spiritual support, this response does not directly address the client’s concern regarding fertility. The nurse’s role is to provide accurate information, and a chaplain might not be the most appropriate resource for discussing fertility concerns. It may be important to refer the client to a fertility specialist or oncologist for more detailed guidance, but this response avoids the core issue.

Summary:

The best response is A because it provides accurate, relevant information regarding the potential effects of cancer therapy on fertility. It helps manage the client’s expectations by acknowledging that cancer treatments can impact fertility, without making overly optimistic or dismissive statements.

The correct answer is C: When a client has a history of 2 or more seizures more than 24 hours apart.|

Explanation for the correct answer:

C. When a client has a history of 2 or more seizures more than 24 hours apart

Epilepsy is diagnosed when a person has had two or more unprovoked seizures that occur more than 24 hours apart. This is the key distinction between a single seizure (which could be caused by many things, such as a head injury, fever, or other temporary causes) and epilepsy, which is a chronic condition where the individual has recurrent, unprovoked seizures.

Why the other options are incorrect:

A. Because an acute condition has caused the seizures you have had

This response is not accurate because the diagnosis of epilepsy requires the seizures to be unprovoked and not due to an acute condition (such as a fever or head injury). Seizures caused by an acute condition are not considered epilepsy.

B. When a client has had a seizure that has lasted more than 5 minutes

A seizure lasting more than 5 minutes is a medical emergency known as status epilepticus. While this is a serious situation, it does not define epilepsy. Epilepsy is characterized by recurrent unprovoked seizures, not necessarily by the duration of a single seizure.

D. Because there is no known cause for the seizures you have had

While it’s true that some cases of epilepsy have no identifiable cause (idiopathic epilepsy), epilepsy can also be caused by brain injury, infections, or genetic factors. The key to diagnosing epilepsy is the recurrence of unprovoked seizures, not necessarily the absence of a known cause.

Summary:

Epilepsy is diagnosed when a person experiences two or more unprovoked seizures that are more than 24 hours apart. This distinguishes epilepsy from a single isolated seizure that could be caused by a temporary or acute condition. Other options like duration of a seizure or the absence of a known cause are not sufficient to diagnose epilepsy.

The correct answer is A: Discuss implementing an advanced directive

Explanation for the correct answer:

A. Discuss implementing an advanced directive

When a client is diagnosed with metastatic lung cancer involving the brain, it is essential to plan for future care. This may include discussions about the client's wishes regarding life-sustaining treatment, preferences for end-of-life care, and the designation of a healthcare proxy or durable power of attorney. An advanced directive allows the client to express their wishes regarding medical interventions if they are no longer able to communicate their preferences. This is a critical part of managing the care of a client with advanced cancer and should be discussed early in the process.

Why the other options are wrong:

B. Explain the use of chemo for brain involvement

Chemotherapy is typically not very effective at treating brain metastasis because most chemotherapy drugs have difficulty crossing the blood-brain barrier. Whole-brain radiation therapy or stereotactic radiosurgery are more commonly used to treat brain metastases. While chemotherapy may be part of the treatment plan for lung cancer itself, it is not the primary intervention for brain metastasis, and this is a less pressing intervention to address in the given scenario.

C. Teach the client to discontinue driving

While brain metastasis can cause neurological symptoms such as seizures, dizziness, and cognitive impairment, which may impair a person's ability to drive safely, teaching the client to discontinue driving is not an immediate intervention. The nurse should assess the client’s neurological status and consult with the healthcare provider about any restrictions or precautions regarding driving. However, this is a more individualized concern and can be discussed later in the course of care.

D. Have the significant other make decisions for the client

While the significant other may play a critical role in supporting the client, decisions regarding medical care should be based on the client’s wishes and autonomy, especially if the client is able to make their own decisions. If the client is unable to make decisions, then the significant other or a designated healthcare proxy may need to make decisions, but it is important to first discuss these issues with the client if possible.

Summary:

The most appropriate intervention for a client with metastatic lung cancer to the brain is to discuss implementing an advanced directive. This allows the client to express their wishes about future care, including end-of-life decisions. The other options (explaining chemotherapy, teaching driving cessation, or having the significant other make decisions) may be appropriate later, but addressing the client’s wishes regarding care is the most pressing and important intervention at this stage.

The correct answer is A: Hgb 7.4 and Hct 21.8

Explanation for the correct answer:

A. Hgb 7.4 and Hct 21.8

Bone marrow suppression is a common side effect of chemotherapy, and it leads to decreases in various blood cell counts. Hgb (hemoglobin) and Hct (hematocrit) are important measures of red blood cells, and low values in these indicate anemia, which is a direct consequence of bone marrow suppression. A hemoglobin level of 7.4 g/dL (normal range is typically 12-16 g/dL for women) and a hematocrit of 21.8% (normal range is usually 36-46% for women) are significantly low and indicate bone marrow suppression, leading to a reduced ability to carry oxygen and potentially causing symptoms such as fatigue, weakness, and dizziness.

Why the other options are wrong:

B. diarrhea & potassium 2.9

While diarrhea and a potassium level of 2.9 mEq/L (which is low, as normal is 3.5-5.0 mEq/L) may be concerning, they do not directly indicate bone marrow suppression. Diarrhea can be a side effect of chemotherapy, but the low potassium level is more indicative of electrolyte imbalance rather than a sign of bone marrow suppression.

C. platelets 250,000

A platelet count of 250,000 is within the normal range (150,000-450,000). Bone marrow suppression often causes a low platelet count (thrombocytopenia), which would result in a higher risk for bleeding and bruising. Since the platelet count here is normal, it does not indicate bone marrow suppression.

D. WBC 5,000

A white blood cell count of 5,000 is within the normal range (4,000-11,000). Bone marrow suppression typically results in neutropenia (low white blood cell count), which increases the risk of infection. Since the WBC count is normal, this is not a sign of bone marrow suppression.

Summary:

Option A (low hemoglobin and hematocrit) is the correct answer because these values indicate anemia, which is a common manifestation of bone marrow suppression caused by chemotherapy. The other options (B, C, D) do not reflect bone marrow suppression.

The correct answer is C: Rapidly administer IV infusion of 0.9% sodium chloride.

Explanation for the correct answer:

C: Rapidly administer IV infusion of 0.9% sodium chloride

Diabetic ketoacidosis (DKA) is characterized by severe dehydration due to high blood glucose levels and osmotic diuresis. One of the first steps in treating DKA is to replenish fluid volume with an IV infusion of normal saline (0.9% sodium chloride). The initial infusion is typically given rapidly to correct dehydration and improve circulation. Normal saline is the preferred solution for rehydration, as it helps to restore intravascular volume without affecting blood sugar levels.

Why the other options are incorrect:

A: Admin IV infusion of regular insulin at 0.3 unit/kg/hr

While insulin is an essential part of DKA treatment, the initial dose of insulin typically begins at 0.1 unit/kg/hr as a continuous IV infusion after the fluid resuscitation is started. The prescribed rate of 0.3 unit/kg/hr is too high for the initial stage of treatment. The purpose of insulin is to lower blood glucose and reverse ketosis, but it should not be given too rapidly at the beginning due to the risk of causing hypoglycemia or rapid shifts in electrolytes.

B: Admin slow IV infusion of 3% sodium chloride

3% sodium chloride (hypertonic saline) is used in cases of severe hyponatremia (low sodium levels), not in the treatment of DKA. For DKA, normal saline (0.9% sodium chloride) is used for initial fluid replacement, and only if hyponatremia is present, or there is an indication of cerebral edema, would hypertonic saline be considered.

D: Add glucose to the IV infusion when blood glucose is 350

In DKA, the glucose level should not be lowered too quickly. Initially, glucose should be reduced at a steady pace with insulin therapy. Glucose is added to the IV infusion when blood glucose reaches around 200-250 mg/dL to prevent hypoglycemia. Adding glucose too early (at 350 mg/dL) can result in unnecessary complications, as the main goal in the early stages is to correct hyperglycemia and ketosis.

Summary:

In the treatment of DKA, the priority is fluid resuscitation using 0.9% sodium chloride (normal saline). After fluid volume is corrected, insulin therapy is then started at a lower rate (0.1 unit/kg/hr) to reduce blood glucose. The administration of hypertonic saline (3% sodium chloride) or adding glucose to the infusion at inappropriate times is not part of the initial management.

The correct answer is D: You need to avoid close contact with others until the doctor determines you are no longer emitting radiation from your body.

Explanation for the correct answer:

Radioactive iodine treatment involves the use of radioactive iodine to treat conditions such as hyperthyroidism or thyroid cancer. After the treatment, the body may still emit radiation for a period of time. It is crucial to avoid close contact with others, especially those who are pregnant, children, or individuals with compromised immune systems, to prevent radiation exposure. The healthcare provider will give specific instructions on when it is safe to resume normal interactions with others.

Why the other options are wrong:

A) You will immediately start thyroid replacement therapy after radioactive iodine treatment.

While it is true that many patients will require thyroid hormone replacement after radioactive iodine treatment (because the treatment can destroy thyroid tissue), not all patients start therapy immediately. Some patients may have sufficient thyroid function following the treatment, and thyroid replacement therapy may be started later if hypothyroidism develops. It is not immediate for everyone.

B) Your partner can feed breast milk to your baby if you pump it.

This is incorrect because radioactive iodine can pass into breast milk, potentially exposing the baby to harmful radiation. Most guidelines recommend discontinuing breastfeeding during and after radioactive iodine therapy, and patients should discuss safe breastfeeding options with their healthcare provider.

C) You can try to get pregnant 2 months after the treatment.

This is generally incorrect because pregnancy should be avoided for a longer period, typically around 6 to 12 months after radioactive iodine treatment. The reason is to ensure that the radiation has cleared from the body before conceiving. Early pregnancy may pose risks to the developing fetus, and it is best to follow the healthcare provider’s advice on timing conception.

Summary:

The most appropriate action after radioactive iodine treatment is to avoid close contact with others until a healthcare provider confirms that the radiation has cleared from the body. This prevents exposing others, especially vulnerable populations, to potential radiation. Other actions like starting thyroid replacement therapy or trying to get pregnant should be based on specific medical evaluation and cannot be generalized immediately after the treatment.

The correct answer is A: Identifying the underlying cause.

Explanation for the correct answer:

A. Identifying the underlying cause

Delirium is typically a symptom of an underlying medical issue, such as infection, medication side effects, metabolic disturbances, or other acute conditions. The priority in treating delirium is to identify and address the underlying cause. If the underlying cause, such as a urinary tract infection, dehydration, or electrolyte imbalance, is treated, the delirium may resolve or improve. Identifying the cause is critical to providing effective treatment and preventing further complications.

Why the other options are incorrect:

B. Keeping the environment quiet

While maintaining a quiet environment can help reduce stimulation for a client with delirium, it is not the priority. Environmental modifications are helpful but will not address the root cause of the delirium. Identifying and treating the underlying cause is more urgent.

C. Reorienting the client often

Reorienting the client is important to reduce confusion and anxiety in delirium, but it is not the priority. While reorientation can help, it will not be effective unless the underlying cause is treated. Reorienting the client should be done in conjunction with addressing the root cause.

D. Monitoring nutritional intake

Monitoring nutrition is important for overall health, but it is not the priority in the immediate treatment of delirium. Nutritional support can be a part of the overall care plan, especially if the delirium is associated with malnutrition or dehydration, but identifying and treating the underlying cause should be the first step.

Summary:

`The priority for treating delirium is identifying the underlying cause because delirium is often the result of an acute medical condition. Addressing the cause will be key in managing and resolving the symptoms. While environmental modifications, reorientation, and nutritional monitoring are all important aspects of care, they are secondary to identifying and addressing the underlying medical issue causing the delirium.
