Medical Surgical Exam 4 (NSG 123)

The correct answer is C: nebulized racemic epinephrine

Explanation for the correct answer:

Nebulized racemic epinephrine is commonly used in the treatment of respiratory distress with stridor associated with RSV (respiratory syncytial virus). Stridor indicates upper airway obstruction, and racemic epinephrine is a bronchodilator that works by reducing airway swelling and relieving stridor. It helps to open the airways and is typically used in cases of severe bronchiolitis, which is the most common manifestation of RSV in young children. The nebulized form allows the medication to be delivered directly to the airways, providing relief for airway inflammation.

Why the other options are wrong:

A. IV antibiotics

IV antibiotics are not indicated for RSV because RSV is a viral infection, and antibiotics are only effective for bacterial infections. The treatment for RSV is primarily supportive, focusing on hydration, oxygen therapy, and bronchodilators. Antibiotics may be used if a secondary bacterial infection is suspected, but they are not part of the routine treatment for RSV itself.

B. IV steroids

While steroids can be useful in treating inflammatory conditions like asthma, they are generally not recommended for routine treatment of RSV, as RSV is caused by a viral infection, and steroids have not been shown to significantly improve outcomes in RSV infections. Steroids may sometimes be used in specific situations, but they are not typically part of standard RSV treatment.

D. Alternating doses of acetaminophen & ibuprofen

Acetaminophen and ibuprofen are typically used to reduce fever and manage pain, but they do not address the underlying respiratory issues caused by RSV. While these medications may help with fever or discomfort, they do not treat the airway obstruction or stridor associated with RSV, and thus would not be the first-line treatment in this case.

Summary:

The correct treatment for a child with respiratory distress and stridor due to RSV is nebulized racemic epinephrine (C), which helps to reduce airway swelling and improve breathing. IV antibiotics (A), IV steroids (B), and alternating doses of acetaminophen and ibuprofen (D) are not appropriate treatments for RSV-related respiratory distress, as RSV is a viral infection and these options do not address the underlying airway obstruction or inflammation caused by the virus.

The correct answer is B: instruct client to use electric razor when shaving

Explanation for the correct answer:

The lab results provided suggest that the client has thrombocytopenia (low platelet count), which is indicated by a platelet level of 22 (normal range for platelets is generally 150,000-450,000 per microliter). A platelet count that low increases the risk of bleeding, and special precautions are necessary to prevent injury or trauma that might cause excessive bleeding.

B. Instruct client to use electric razor when shaving

An electric razor is less likely to cause cuts and nicks compared to a traditional razor. Since the client has thrombocytopenia (low platelets), the risk of bleeding is high. Using an electric razor minimizes the risk of cutting the skin and causing bleeding, which is crucial to avoid in this situation.

Why the other options are wrong:

A. Encourage client to eat foods high in iron

Although the RBC count of 2.1 is low (suggesting the client might have anemia), the platelet count is the more pressing issue in this scenario due to the significantly low platelet level. The immediate concern is preventing bleeding, not addressing anemia through iron-rich foods. Therefore, this option is not the most appropriate given the lab results.

C. Discuss importance of limiting sodium in the diet

There is no indication from the lab results (with a normal sodium level of 139 mEq/L) that the client has a sodium imbalance or needs to limit sodium intake. The primary concern here is the low platelet count and preventing bleeding, not sodium intake.

D. Instruct the family to limit visits to once a week

This intervention is more appropriate for a patient who is neutropenic (low WBC count), as it would help reduce the risk of infections. However, the WBC count of 4.3 is within the normal range (approximately 4,000-11,000 per microliter). The priority for this patient should be addressing the bleeding risk rather than limiting family visits, as their immune function does not seem to be compromised.

Summary:

For a client with low platelet count (thrombocytopenia), the main concern is preventing bleeding. Therefore, the best intervention is to use an electric razor to avoid cuts when shaving. The other options either do not address the immediate issue or are not relevant based on the lab findings.

The correct answer is C: glucagon (Glucagen)

Explanation for the correct answer:

C. glucagon (Glucagen)

Glucagon is the appropriate drug for treating severe hypoglycemia (low blood sugar) when a patient is unable to take oral glucose (e.g., unconscious or unresponsive). It works by stimulating the liver to release glucose into the bloodstream, which raises the blood sugar levels quickly. Glucagon is commonly administered subcutaneously or intramuscularly in emergency situations, typically by a caregiver or healthcare provider.

Why the other options are incorrect:

A. acarbose (Precose)

Acarbose is an alpha-glucosidase inhibitor used in the treatment of type 2 diabetes to delay the absorption of carbohydrates in the intestines, thus preventing postprandial blood sugar spikes. It does not treat hypoglycemia. In fact, acarbose can sometimes cause delayed hypoglycemia if combined with insulin or sulfonylureas, but it is not used to treat it.

B. propranolol (Inderal)

Propranolol is a beta-blocker used to treat conditions like hypertension, angina, and arrhythmias. It is not used to treat hypoglycemia and could mask symptoms of hypoglycemia, such as tremors, tachycardia, and anxiety, making it even harder for patients to recognize the low blood sugar early.

D. bumetanide (Bumex)

Bumetanide is a loop diuretic used to treat conditions like edema and hypertension. It is not related to treating hypoglycemia and is not used in the management of low blood sugar.

Summary:

Glucagon (Glucagen) is the correct treatment for severe hypoglycemia. It works by stimulating the release of glucose from the liver, rapidly raising blood sugar levels in an emergency. The other options listed do not address hypoglycemia and are used for different medical conditions.

The correct answer is D: NPH and regular insulin can be combined in one syringe by first drawing up the NPH.

Explanation for the correct answer:

This statement is incorrect, and it indicates that more education is needed. When combining NPH (intermediate-acting) insulin and regular (short-acting) insulin in one syringe, the correct procedure is to draw up the regular insulin first, followed by the NPH insulin. The reason for this order is to prevent contamination of the short-acting insulin (regular) with the longer-acting insulin (NPH), which could affect the action and efficacy of the regular insulin.

Why the other options are correct:

A: Bedtime snacks are provided to prevent hypoglycemic reaction at night.

This statement is correct. Bedtime snacks can be beneficial for some individuals on insulin therapy, especially those taking intermediate-acting insulin such as NPH. It helps to prevent hypoglycemia that may occur overnight when the insulin is peaking. However, not all patients require bedtime snacks; it depends on their individual insulin regimen and blood glucose patterns.

B: Food should be provided to the client at the peak action time of the insulin.

This statement is correct. Providing food around the peak action time of insulin helps prevent hypoglycemia. For instance, rapid-acting insulins peak within 30 to 90 minutes after administration, so providing food at that time helps stabilize blood glucose levels.

C:Clients should be provided information about hypoglycemia and its management.

This statement is correct. Educating patients about hypoglycemia and its management is crucial for safety. Patients should know the symptoms of hypoglycemia and how to treat it, such as consuming fast-acting carbohydrates (e.g., glucose tablets, juice) to raise blood sugar levels quickly.

Summary:

The statement about combining NPH and regular insulin in one syringe is incorrect because the proper technique is to draw the regular insulin first, followed by the NPH insulin. The other statements about bedtime snacks, peak action times of insulin, and hypoglycemia education are correct.

The correct answer is D: Administer a prescribed injectable glucagon.

Explanation for the correct answer:

D. Administer a prescribed injectable glucagon.

The symptoms described—headache, nausea, diaphoresis (sweating), and loss of consciousness—are consistent with hypoglycemia, which is a common complication in clients with diabetes mellitus. When a client loses consciousness due to hypoglycemia and is unable to take oral glucose, the nurse should administer injectable glucagon. Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream, raising the blood sugar levels and potentially reversing the hypoglycemic state.

Why the other options are incorrect:

A. Assess the client for the need for compressions.

Compression for cardiopulmonary resuscitation (CPR) would be necessary if the client was not breathing or had no pulse, which is not indicated here. The scenario suggests hypoglycemia, not a cardiac arrest situation.

B. Perform a sternal rub to arouse the client.

A sternal rub may be used to try to arouse an unconscious client, but it would not address the underlying cause of the unconsciousness, which is likely hypoglycemia. The nurse should take immediate action to correct the hypoglycemia, such as administering glucagon if the client is unconscious.

C. Provide 15 g of a fast-acting carbohydrate.

While this is the correct intervention for a conscious client experiencing mild hypoglycemia, the client in this scenario is unconscious. If the client cannot swallow safely, oral carbohydrates should not be administered as there is a risk of aspiration. Injectable glucagon is indicated for unconscious clients.

Summary:

The priority action for a client who is unconscious due to suspected hypoglycemia is to administer injectable glucagon to raise the client's blood glucose levels. This intervention is vital in preventing further complications and restoring consciousness.

The correct answer is B: limit fresh fruits & flowers, D. have clients use soft-bristle toothbrush, E. screen visitors for infectious disease

Explanation for the correct answer:

Neutropenia is a condition characterized by a low neutrophil count, which makes patients more susceptible to infections. On an oncology unit, neutropenic precautions are vital to protect these patients from potential infections. Here’s a breakdown of why the selected interventions are correct:

B. Limit fresh fruits & flowers

Fresh fruits and flowers, especially those with a lot of moisture like fresh flowers, can harbor bacteria and fungi that may increase the risk of infection for a neutropenic patient. Fresh fruits can also contain microbes that are harder to wash away. Limiting them helps minimize the risk of infections.

D. Have clients use soft-bristle toothbrush

Using a soft-bristle toothbrush reduces the risk of oral mucosal injury and bleeding, which could lead to infections in neutropenic patients. Brushing with a soft-bristle toothbrush minimizes the potential for trauma in the mouth, reducing the likelihood of an infection.

E. Screen visitors for infectious disease

Screening visitors helps ensure that individuals who might be infected or carrying germs that could lead to infection are kept away from neutropenic patients. This is a vital part of reducing the patient's exposure to infectious agents.

Why the other options are wrong:

A. Hold all venipuncture sites for at least 5 minutes

While it's important to hold venipuncture sites to reduce the risk of bleeding, this is not specific to neutropenia precautions. The primary concern with neutropenic patients is infection control, not bleeding. This does not directly relate to protecting the patient from infection.

C. Place all clients in reverse isolation

Reverse isolation is generally used for immunocompromised patients to prevent external contamination. However, not all patients with neutropenia require this. Instead, the focus should be on using other precautions like limiting exposure to infections (e.g., limiting fresh foods and screening visitors). Reverse isolation is typically used when severe neutropenia is present, but it is not universally required for all patients with neutropenia.

Summary:

For patients with neutropenia, effective precautions include limiting fresh fruits and flowers, using soft-bristle toothbrushes, and screening visitors for infectious diseases. These measures help reduce the risk of infection, which is the primary concern for neutropenic patients. Holding venipuncture sites and reverse isolation are not as directly related to preventing infections in this context.

The correct answer is A: Heart disease

Explanation for the correct answer:

A. Heart disease:

Hypothyroidism, especially in older adults, increases the risk for heart disease. This is due to the effects of low thyroid hormone levels on cholesterol metabolism. Hypothyroidism can lead to elevated levels of total cholesterol and low-density lipoprotein (LDL), which increase the risk of atherosclerosis and coronary artery disease. Additionally, hypothyroidism can slow heart rate and reduce cardiac output, further contributing to cardiovascular issues.

Why the other options are incorrect:

B. Chronic lung disorders:

Hypothyroidism is not primarily associated with chronic lung disorders. While hypothyroidism can lead to respiratory muscle weakness and a slow respiratory rate, it does not significantly increase the risk of chronic lung conditions such as chronic obstructive pulmonary disease (COPD).

C. Neurological disorders:

While hypothyroidism can cause cognitive impairments, depression, and slowed mental function, it does not directly increase the risk of neurological disorders like Alzheimer's disease or other degenerative neurological conditions. The primary concerns with hypothyroidism in older adults relate to its cardiovascular and metabolic effects.

D. Renal disease:

Although hypothyroidism can affect kidney function, it is not a major direct risk factor for renal disease. However, hypothyroidism can contribute to fluid retention and edema, which can indirectly affect renal function, but heart disease is a more direct concern for those with hypothyroidism.

Summary:

Older adults with hypothyroidism are at an increased risk for heart disease due to elevated cholesterol levels and the impact of low thyroid hormone on cardiac function. This makes cardiovascular health a key concern in the management of hypothyroidism in older adults.

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 B: 10 minutes before meals

Explanation for the correct answer:

B) 10 minutes before meals:

Lispro (Humalog) is a rapid-acting insulin. It should be administered 10 to 15 minutes before meals to ensure that the insulin starts working to lower blood glucose levels when the food is being digested. Rapid-acting insulins like lispro begin to work quickly (within 15 minutes) and peak around 30-90 minutes after injection, which aligns well with the timing of meals.

Why the other options are incorrect:

A) 30 minutes before meals:

Rapid-acting insulins like lispro work much faster than long-acting insulins, so administering it 30 minutes before meals would not align with the timing of the insulin’s peak and action. This could cause a mismatch in insulin coverage and food intake.

C) 2 hours before meals:

Administering lispro insulin 2 hours before meals would not be effective because by the time the client eats, the insulin would have already peaked and its action would be waning. This could lead to hypoglycemia (low blood sugar) before the meal even starts.

D) 1 hour before meals:

Administering lispro 1 hour before meals could also result in a mismatch between the onset of action and the timing of the meal. By the time the food is digested, the insulin may already have reached its peak, leading to a higher risk of hypoglycemia during or after the meal.

Summary:

Lispro (Humalog), a rapid-acting insulin, should be administered 10 minutes before meals to ensure it starts working as the food is being digested, effectively lowering the blood sugar levels when they rise after eating. Administering it too early or too late can cause an ineffective insulin response and increase the risk of hypoglycemia or inadequate blood sugar control.
