Nursing Elites

1. In a patient with chronic kidney disease, which of the following is a common electrolyte imbalance?

• A. Hyperkalemia.
• B. Hypokalemia.
• C. Hypernatremia.
• D. Hyponatremia.

Correct answer: A

Rationale: Hyperkalemia is a common electrolyte imbalance in chronic kidney disease. In chronic kidney disease, the kidneys' reduced function leads to the decreased excretion of potassium, resulting in elevated serum potassium levels. This can be dangerous as hyperkalemia can lead to life-threatening arrhythmias. Hypokalemia (Choice B) is less common in chronic kidney disease as the impaired kidneys tend to retain potassium. Hypernatremia (Choice C) is more commonly seen in conditions such as dehydration, not primarily in chronic kidney disease. Hyponatremia (Choice D) is also possible in chronic kidney disease but is less common compared to hyperkalemia.

2. A client who had a C-5 spinal cord injury 2 years ago is admitted to the emergency department with the diagnosis of autonomic dysreflexia secondary to a full bladder. Which assessment finding should the nurse expect this client to exhibit?

• A. Complaints of chest pain and shortness of breath
• B. Hypotension and venous pooling in the extremities
• C. Profuse diaphoresis and severe, pounding headache
• D. Pain and burning sensation upon urination and hematuria

Correct answer: C

Rationale: Autonomic dysreflexia is a life-threatening condition commonly seen in clients with spinal cord injuries above the T6 level. It is characterized by a sudden onset of excessively high blood pressure due to a noxious stimulus below the level of injury, often a distended bladder. The exaggerated sympathetic response leads to vasoconstriction, resulting in symptoms such as profuse diaphoresis (sweating) and a severe, pounding headache. These symptoms are the body's attempt to lower blood pressure. Complaints of chest pain and shortness of breath (Choice A) are not typical findings in autonomic dysreflexia. Hypotension and venous pooling (Choice B) are opposite manifestations of autonomic dysreflexia, which is characterized by hypertension. Pain and burning sensation upon urination and hematuria (Choice D) are indicative of a urinary tract infection and not specific to autonomic dysreflexia.

3. A client with diabetes mellitus who is taking NPH insulin (Humulin N) in the evening is most likely to become hypoglycemic shortly after midnight because this insulin peaks in 6 to 8 hours. What intervention should the nurse recommend to help prevent hypoglycemia while the client is sleeping?

• A. Eat a bedtime snack.
• B. Avoid physical activity.
• C. Take half the usual dose of insulin.
• D. Discontinue insulin until the next meal.

Correct answer: A

Rationale: Eating a bedtime snack is the most appropriate intervention to prevent hypoglycemia during the night when NPH insulin peaks. This snack helps maintain blood glucose levels and counteracts the risk of hypoglycemia. Avoiding physical activity is not recommended as it can further lower blood sugar levels. Taking half the usual dose of insulin can lead to inadequate control of blood sugar levels. Discontinuing insulin until the next meal can result in uncontrolled hyperglycemia, especially during the peak action of NPH insulin.

4. The nurse is preparing to give trimethoprim-sulfamethoxazole (TMP-SMX) to a patient and notes a petechial rash on the patient’s extremities. The nurse will perform which action?

• A. Hold the dose and notify the provider.
• B. Request an order for a blood glucose level.
• C. Request an order for a BUN and creatinine level.
• D. Request an order for diphenhydramine (Benadryl).

Correct answer: A

Rationale: When a patient on TMP-SMX presents with a petechial rash, it can be indicative of a severe adverse reaction such as thrombocytopenia or a hypersensitivity reaction. The appropriate action for the nurse to take in this situation is to hold the dose of TMP-SMX and notify the healthcare provider immediately. This is crucial to prevent further administration of a medication that may be causing a serious adverse effect. Requesting a blood glucose level (Choice B) is not relevant in this scenario as the patient's presentation is suggestive of a skin-related issue rather than a glucose-related problem. Similarly, requesting a BUN and creatinine level (Choice C) would not address the immediate concern of a petechial rash and its association with TMP-SMX. Requesting an order for diphenhydramine (Choice D) may help manage itching or mild allergic reactions but is not the priority when a petechial rash is observed, as it may indicate a more severe reaction requiring immediate intervention.

5. After a lumbar puncture, into which position does the nurse assist the client?

• A. Flat
• B. Semi-Fowler
• C. Side-lying with the head of the bed elevated
• D. Sitting up in a recliner with the feet elevated

Correct answer: A

Rationale: After a lumbar puncture, the client should be positioned flat. This position helps prevent post-procedure spinal headaches and cerebrospinal fluid leakage. Keeping the client flat for up to 12 hours is crucial in minimizing these risks. Choices B, C, and D are incorrect because elevating the head of the bed or sitting up can increase the risk of complications by altering the pressure in the spinal canal, potentially leading to headaches and fluid leakage.
