How does hyponatremia place the patient at risk?

A. Seizures

B. Fatigue

C. Cardiac dysrhythmias

D. Muscle weakness

Correct Answer: C
Rationale: Hyponatremia places the patient at risk for cardiac dysrhythmias. While hyponatremia can lead to seizures due to cerebral edema caused by fluid imbalance, the most immediate and life-threatening risk is cardiac dysrhythmias. Low sodium levels can disrupt the heart's electrical activity, potentially leading to fatal arrhythmias. Although fatigue and muscle weakness are symptoms of hyponatremia, cardiac dysrhythmias pose the most critical concern as they can have severe consequences.

What is the priority action if a patient experiences hypoglycemia after an insulin dose?

• A. Check the patient's blood glucose level
• B. Administer IV dextrose
• C. Document the incident
• D. Continue monitoring the patient

Correct Answer: A
Rationale: The priority action when a patient experiences hypoglycemia after an insulin dose is to check the patient's blood glucose level. This is crucial to confirm hypoglycemia before initiating any treatment. While administering IV dextrose may be necessary if the patient's blood glucose level is critically low, confirming hypoglycemia is essential to guide appropriate interventions. Documenting the incident is important for documentation purposes but is not the immediate priority when the patient's safety is at risk. Continuing to monitor the patient is essential, but it should follow the confirmation and initial management of hypoglycemia.

What is the primary concern in a patient with a low CD4 T-cell count in HIV?

• A. Increased risk of infection
• B. Increased risk of bleeding
• C. Decreased immunity leading to opportunistic infections
• D. Increased risk of cardiac complications

Correct Answer: A
Rationale: The correct answer is A: Increased risk of infection. In HIV patients with a low CD4 T-cell count, the primary concern is the increased susceptibility to infections due to compromised immunity. This compromised immune system can lead to various infections, making infection control crucial. Choice B, increased risk of bleeding, is not directly associated with a low CD4 count in HIV. Option C, decreased immunity leading to opportunistic infections, conveys a similar concern as the correct answer but lacks specificity. Choice D, increased risk of cardiac complications, is not typically the primary concern in HIV patients with a low CD4 count, as infections and opportunistic diseases pose more immediate threats to health.

What are the expected symptoms in a patient experiencing a thrombotic stroke?

• A. Gradual loss of function on one side of the body
• B. Sudden loss of consciousness
• C. Seizures and convulsions
• D. Severe headache and vomiting

Correct Answer: A
Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' Thrombotic strokes typically result in a gradual onset of symptoms due to a blockage in a blood vessel in the brain, leading to a slow progression of neurological deficits. Choices B, C, and D are incorrect because sudden loss of consciousness, seizures, convulsions, severe headache, and vomiting are more commonly associated with other types of strokes or medical conditions, such as hemorrhagic strokes, epilepsy, or migraines.

What is the first-line treatment for a patient experiencing wheezing and coughing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Methylprednisolone 100 mg IV
• C. Cromolyn 20 mg via nebulizer
• D. Aminophylline 500 mg IV

Correct Answer: A
Rationale: The correct answer is A: Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction as it quickly opens the airways, providing rapid relief. Choice B, Methylprednisolone 100 mg IV, is a systemic corticosteroid that may be used in severe cases to reduce inflammation but is not the initial treatment for acute wheezing. Choice C, Cromolyn 20 mg via nebulizer, is a mast cell stabilizer that is more commonly used for prophylaxis rather than acute relief in allergic conditions. Choice D, Aminophylline 500 mg IV, is a bronchodilator that is less commonly used now due to its narrow therapeutic window and potential for toxicity, making it less preferred than Albuterol for initial treatment of wheezing.
