Medical Surgical Exam 4 (NSG 123)

The correct answer is C: pH 6.98; PaO2 100; PaCO2 30; HCO3- 18

Explanation for the correct answer:

C. pH 6.98; PaO2 100; PaCO2 30; HCO3- 18

This arterial blood gas (ABG) finding is consistent with salicylate (aspirin) toxicity, which can cause metabolic acidosis with respiratory compensation. Aspirin toxicity leads to two primary metabolic disturbances:

Respiratory alkalosis due to increased respiratory rate (RR 42 and deep breathing as seen in the client) from stimulation of the respiratory centers in the brainstem.

Metabolic acidosis due to salicylates directly affecting the metabolism and causing an increase in lactic acid and other acidic metabolites. This is reflected in the low pH (6.98), low bicarbonate (HCO3- 18), and respiratory compensation (decreased PaCO2 30).

Salicylate toxicity causes both respiratory alkalosis and metabolic acidosis, and the body compensates for these imbalances. The pH is low due to the combined effects of both conditions.

Why the other options are wrong:

A. pH 7.68; PaO2 96, PaCO2 38; HCO3- 28

This ABG finding indicates alkalosis (pH 7.68) and normal PaCO2 and HCO3- levels. It does not fit with salicylate toxicity, which typically causes acidotic changes, not alkalosis.

B. pH 7.48; PaO2 100, PaCO2 28; HCO3- 23

This ABG indicates respiratory alkalosis, which could occur from hyperventilation (as seen in aspirin toxicity), but there is no evidence of metabolic acidosis in this result, which is a key component of aspirin toxicity.

D. pH 7.58; PaO2 96; PaCO2 38; HCO3- 29

This ABG reflects alkalosis with a high bicarbonate level, which is not consistent with the metabolic acidosis expected in aspirin toxicity. The pH is high, and there is no evidence of an acidic disturbance.

Summary:

The expected ABG findings for a client with aspirin toxicity (salicylate poisoning) would include metabolic acidosis (low pH and bicarbonate) and respiratory compensation (increased respiratory rate to compensate for acidosis, causing decreased PaCO2). This matches option C with the low pH (6.98), low bicarbonate (18), and slightly reduced PaCO2 (30). Other options indicate alkalosis, which is inconsistent with the typical presentation of aspirin toxicity.

The correct answer is C: we will swab your child's nose & send that specimen for testing

Explanation for the correct answer:

The diagnosis of Respiratory Syncytial Virus (RSV) is typically confirmed by nasal swab testing, which involves collecting a sample from the nasal passages and sending it to a laboratory for polymerase chain reaction (PCR) testing or antigen detection. This is the most accurate and commonly used method for diagnosing RSV. The sample is processed to identify the virus' genetic material or proteins.

Why the other options are wrong:

A. we will do a simple blood test to determine whether your child has RSV

There is no specific blood test that can definitively diagnose RSV. RSV is typically diagnosed through respiratory samples, not blood tests. A blood test may be used to assess overall health or look for complications, but it is not used to diagnose RSV itself.

B. there is no specific test for RSV, the diagnosis is based on symptoms

While symptoms (such as cough, wheezing, and difficulty breathing) can suggest RSV, a specific test is required to confirm the diagnosis. Symptom-based diagnosis alone can be unreliable because symptoms of RSV overlap with other respiratory infections, such as the flu or common cold.

D. we will have to send a viral culture to an outside lab for testing

Although viral cultures can be used to diagnose RSV, they are less commonly used due to their longer turnaround time. Rapid diagnostic tests, such as PCR or antigen tests from nasal swabs, provide faster results and are more commonly used in clinical settings.

Summary:

The best response is to inform the parent that a nasal swab will be collected and sent for testing (C), as this is the most common and accurate method for diagnosing RSV. The other options (A, B, D) either incorrectly describe the testing method or are outdated approaches.

 The correct answers are

A .drink 2 L fluids daily

B. monitor blood glucose every 4 hr when ill"

C.  admin insulin as prescribed when ill

E. report ketones in the urine after 24 hr of illnes

Explanation for the correct answers:

A. Drink 2 L fluids daily

Fluids are crucial for preventing dehydration, which can worsen DKA. Drinking enough fluids, typically around 2 liters daily, helps to maintain hydration, supports kidney function, and prevents high blood glucose levels, which can lead to DKA.

B. Monitor blood glucose every 4 hours when ill

During illness, blood glucose can rise even without eating, and the risk of developing DKA increases. Monitoring blood glucose levels every 4 hours allows the client to detect high glucose levels early and take corrective action, such as adjusting insulin doses, to avoid complications like DKA.

C. Administer insulin as prescribed when ill

When ill, the body is under stress, and blood glucose levels may increase due to stress hormones. It is essential to administer insulin as prescribed, even if the client is not eating, to prevent hyperglycemia and the risk of DKA.

E. Report ketones in the urine after 24 hours of illness

The presence of ketones in the urine after 24 hours of illness indicates that the body is breaking down fat for energy due to inadequate insulin. Ketones are a key sign of potential DKA and should be reported to the healthcare provider, especially if they persist after a day of illness, to prevent worsening of the condition.

Why the other option is incorrect:

D. Notify provider when blood glucose is 200

A blood glucose level of 200 mg/dL is not typically a cause for alarm. Many people with diabetes can maintain blood glucose levels up to 200 mg/dL without progressing to DKA. Immediate notification to the provider is generally recommended when blood glucose levels are over 300 mg/dL for extended periods, or if the client has other signs of DKA, such as ketones in the urine or symptoms of dehydration.

Summary:

To prevent DKA, it is crucial to stay hydrated, monitor blood glucose regularly (especially when ill), continue taking insulin as prescribed, and report symptoms such as ketones in the urine. Immediate contact with the healthcare provider is more critical when blood glucose levels are greater than 300 mg/dL or when symptoms of DKA develop, rather than at a glucose level of 200 mg/dL.

The correct answer is D: administer analgesics.

Explanation for the correct answer:

D. Administer analgesics

Acute otitis media (AOM) is a common condition in toddlers, and it is often associated with significant pain due to the inflammation of the middle ear. The priority action is to relieve the child's pain. Administering analgesics, such as acetaminophen or ibuprofen, will help reduce the discomfort and provide relief while other treatments or interventions are initiated.

Why the other options are incorrect:

A. Provide emotional support to the family

Although emotional support is important for the family, the priority action for the nurse in this situation is addressing the child’s pain. Once the pain is managed, emotional support can be provided to the family.

B. Educate family on care of the child

While education is an essential part of care, the priority is to address the child’s pain first. Once the pain is managed, the nurse can educate the family on proper care and follow-up.

C. Provide diversional activity

Diversional activities can be helpful in distracting the child, but the priority is to manage the pain. Once the pain is controlled, diversional activities can be used to keep the child comfortable.

Summary:

The priority action for a toddler with acute otitis media is to administer analgesics to manage the child’s pain. Providing emotional support, educating the family, and offering diversional activities are all important but should come after addressing the child’s immediate comfort.

The correct answer is B: encouraging child to keep hands away from eyes

Explanation for the correct answer:

B. encouraging child to keep hands away from eyes

It can be particularly challenging for young children, such as a 6-year-old, to consistently keep their hands away from their eyes. Children of this age are often unaware of the importance of avoiding rubbing or touching their eyes, especially when they experience discomfort from allergic conjunctivitis, such as itching. Despite repeated reminders, it can be difficult for them to resist touching their eyes, which can worsen symptoms by transferring allergens or irritants directly to the eye area.

Why the other options are easier to implement:

A. washing the child's hands & face when returning from outdoors

This action is fairly easy to implement and can be done routinely when the child comes indoors. It is a helpful step to minimize the transfer of allergens from the environment to the eyes or face.

C. rinsing the child's eyelids with clean washcloth & cool water

This is a simple and soothing method for reducing irritation and is easy to perform. It also helps wash away allergens that might be present around the eyes.

D. making sure child showers & shampoos before bedtime

Although it may take some time and effort, having the child shower and shampoo before bedtime is a practical and beneficial step to remove allergens that may have accumulated in the hair and on the body during the day. It helps reduce the exposure to allergens in bed and during sleep.

Summary:

While all the options are useful in minimizing allergen exposure for a child with allergic conjunctivitis, encouraging a 6-year-old to keep their hands away from their eyes (B) is likely the most difficult action to implement consistently, as young children often touch or rub their eyes instinctively, especially when they are experiencing itching or irritation.

The correct answer is  A: Look directly at the person you are talking to.

Explanation for the correct answer:

A. Look directly at the person you are talking to.

This is the most appropriate advice for a client with Parkinson’s disease who has difficulty speaking. Looking directly at the person enhances non-verbal communication through facial expressions and lip movements, which can help the listener better understand the speaker. It also reinforces social connection and focuses attention, making communication more effective.

Why the other options are incorrect:

B. Stop to take a breath after each word.

This is incorrect because stopping to breathe after each word is unnecessary and may disrupt the natural flow of speech, making it harder to understand and more frustrating for the speaker.

C. Use a hearing aid to improve communication.

This is not appropriate unless the client also has hearing loss. Parkinson’s disease affects speech production, not hearing, so a hearing aid would not address the primary issue in this case.

D. Try to speak louder and faster.

This is incorrect. Clients with Parkinson’s disease often have hypophonia (low speech volume), but encouraging them to speak faster can worsen clarity. Speech therapy usually emphasizes speaking slowly, clearly, and louder, not faster.

Summary:

Clients with Parkinson’s disease who have difficulty speaking should be encouraged to look directly at the person they are speaking to as this enhances non-verbal cues and supports better communication. The other options are either ineffective or inappropriate given the nature of speech difficulties in Parkinson’s disease.

The correct answer is B: you will be given an injection of a radioactive substance

Explanation for the correct answer:

B. you will be given an injection of a radioactive substance

Nuclear imaging involves the use of radioactive substances (called radiopharmaceuticals) to produce images of the inside of the body. The patient typically receives an injection of a radioactive substance, which will be absorbed by certain tissues in the body. This helps the imaging equipment detect areas of concern, such as tumors or abnormal growths, which can help in diagnosing cancer or other conditions. This is the most accurate statement about nuclear imaging.

Why the other options are wrong:

A. the presence of a liver enzyme will be identified

This is incorrect. While liver enzyme levels may be assessed using blood tests, nuclear imaging is not used to identify liver enzymes. Nuclear imaging focuses on creating images to assess how organs and tissues are functioning, rather than identifying specific enzymes.

C. an endoscope will be inserted through the mouth

This is incorrect. An endoscope is used for procedures like endoscopy, which involves inserting a flexible tube with a camera through a body cavity, such as the mouth, to view internal structures. This is a different diagnostic procedure and not part of nuclear imaging.

D. the tumor will be aspirated

This is incorrect. Aspiration refers to the removal of tissue or fluid for examination, usually through a needle (e.g., fine needle aspiration or biopsy). Nuclear imaging does not involve aspiration of tissue; it involves the use of radioactive substances to visualize areas inside the body.

Summary:

For nuclear imaging, the correct information to provide is that the patient will receive an injection of a radioactive substance (B), which is used to help create detailed images of internal structures and identify areas of concern like cancer. Other options involve different diagnostic procedures that are not part of nuclear imaging.

The correct answer is C: You should try to maintain a regular sleep pattern.

Explanation:

A regular sleep pattern is one of the most effective strategies for preventing migraines. Irregular sleep patterns, such as staying up too late or not getting enough sleep, can trigger migraine attacks. Consistent sleep helps regulate bodily functions and may help reduce the frequency of migraines.

Why the other options are incorrect:

A. Chocolate can help decrease stress and prevent headaches.

This statement is incorrect. Chocolate can actually be a trigger for migraines in some people, especially those who are sensitive to caffeine or theobromine. Migraines can be triggered by a variety of foods, including chocolate, due to their components that affect blood vessels and neurotransmitters in the brain.

B. Oral contraceptives are not associated with causing headaches.

This statement is not true. Oral contraceptives (birth control pills) can increase the risk of headaches, especially in women who are prone to migraines. Some women may experience migraines as a side effect of hormonal changes caused by birth control pills.

D. Use bright lighting inside so your eyes do not have to strain.

This advice is incorrect. Bright lighting, particularly fluorescent lights, can actually trigger migraines in some individuals. It's better to use soft lighting and avoid harsh or flickering lights to prevent eye strain and reduce the risk of migraines. Dim lighting and taking regular breaks from screen time can help prevent migraines related to visual strain.

Summary:

Maintaining a regular sleep pattern is one of the key recommendations for preventing migraines. Other strategies include identifying and avoiding personal migraine triggers, such as certain foods or lighting, and managing stress.

The correct answers are:

A) Assist with meals as needed.

B) Monitor for aspiration.

E) Obtain dietary consult.

Explanation for the correct answers:

A) Assist with meals as needed:

In clients with advanced Parkinson's disease, there may be difficulty with fine motor control, muscle rigidity, and tremors that can affect their ability to feed themselves. The nurse should assist with meals to ensure the client receives proper nutrition and to prevent frustration or potential malnutrition due to difficulty eating.

B) Monitor for aspiration:

Aspiration is a significant risk in clients with Parkinson's disease, especially as the disease progresses and dysphagia (difficulty swallowing) becomes more common. The nurse should monitor for signs of aspiration, such as coughing, choking, or changes in breathing pattern, and intervene appropriately to ensure the client’s airway remains clear during meals.

E) Obtain dietary consult:

A dietary consult is important for clients with Parkinson’s disease, particularly in advanced stages, to assess their nutritional needs and swallowing abilities. A dietitian can provide guidance on meal planning, adjusting food consistency (e.g., pureed or thickened foods), and ensuring that the client receives adequate nutrition, especially if there are concerns about weight loss or difficulty eating.

Why the other options are incorrect:

C) Obtain weight monthly:

While monitoring weight is important in managing any chronic disease, obtaining weight on a monthly basis may not be frequent enough for a client with advanced Parkinson’s disease, especially if there are concerns about weight loss or malnutrition. It would be better to monitor weight more frequently to track changes in nutritional status and adjust the care plan accordingly.

D) Provide supplemental feedings:

Although this might be necessary in some cases, the decision to provide supplemental feedings (e.g., tube feeding or liquid supplements) should be based on the client's swallowing ability and nutritional assessment. It’s not a standard intervention without evaluating the client’s specific needs and the advice of a healthcare provider or dietitian.

Summary:

For a client with advanced Parkinson’s disease, interventions should focus on assisting with meals, monitoring for aspiration, and obtaining a dietary consult to ensure proper nutrition and safety. Regular weight monitoring is important, but monthly weight checks may not be frequent enough. Supplemental feedings are only necessary based on the client's specific nutritional and swallowing needs.
