Correct Answer: A

Rationale: The correct answer is A: Monitor fluid balance and administer heparin. For a patient undergoing dialysis, it is crucial to monitor fluid balance to prevent fluid overload or depletion. Administering heparin helps prevent clot formation during the dialysis process. Option B is incorrect as while monitoring blood pressure is essential, preventing clot formation is more directly related to heparin administration. Option C is incorrect because administering medications and monitoring blood chemistry are not the primary interventions for dialysis. Option D is incorrect as while dietary education and protein intake are important for overall health, they are not the key nursing interventions specifically for a patient undergoing dialysis.

Correct Answer: A

Rationale: When educating a patient with hypertension about lifestyle modifications, reducing sodium intake is crucial as excess sodium can contribute to high blood pressure. While increasing physical activity is beneficial for overall health, it is not the primary lifestyle modification specifically targeted at hypertension. Quitting smoking and avoiding alcohol are important for general health but are not the first-line lifestyle modifications recommended for hypertension. Therefore, the correct answer is to reduce sodium intake.

Correct Answer: A

Rationale: The correct answer is A: 'Drooping eyelids.' Ptosis, characterized by drooping of the eyelid, is a classic symptom seen in myasthenia gravis. This occurs due to muscle weakness, particularly in the muscles that control eyelid movement. Choice B, 'Unequal pupils,' is not associated with ptosis and may indicate other neurological issues. Choice C, 'Facial twitching,' is not a typical sign of ptosis but could be related to other conditions like nerve irritation. Choice D, 'Facial droop,' is more commonly seen in conditions affecting the facial nerve, like Bell's palsy, and is not a characteristic feature of myasthenia gravis.

Correct Answer: A

Rationale: The correct signs of hypoglycemia are sweating and trembling. These should be managed by administering glucose to raise blood sugar levels. Headache, confusion, dizziness, fatigue, or increased heart rate are not typical signs of hypoglycemia. Administering insulin in response to hypoglycemia would further lower blood sugar levels, exacerbating the condition.

Correct Answer: B

Rationale: The correct answer is B: Zolpidem. Zolpidem is a sedative-hypnotic medication that can worsen altered mental status, especially in clients who are already aggressive. Therefore, the nurse should clarify this prescription with the provider before administration to ensure it is safe for the client. Choice A, Haloperidol, is an antipsychotic commonly used to manage aggression in clients with altered mental status, making it an appropriate choice in this scenario. Choice C, Morphine, is an opioid analgesic and would not directly impact the client's altered mental status or aggression. Choice D, Lorazepam, is a benzodiazepine used to manage anxiety and agitation, which could be beneficial in this situation but does not have the same potential to exacerbate altered mental status as Zolpidem.
