Correct Answer: B

Rationale: The correct first step in managing a client with delirium is to identify any reversible causes of delirium. This is crucial because addressing the underlying cause can help in resolving delirium more effectively. Administering sedative or antipsychotic medications without addressing the root cause may not be helpful and can even worsen the condition. Limiting environmental stimulation, although important, is not the primary step in managing delirium.

Correct Answer: C

Rationale: The correct answer is C: Serum potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Therefore, the nurse should monitor the client's serum potassium levels to prevent hyperkalemia, which can be a potential side effect of spironolactone. Monitoring total bilirubin levels (A) is not specifically required for clients taking spironolactone. Urine ketones (B) are not directly influenced by spironolactone use. Platelet count (D) is not typically monitored in clients taking spironolactone.

Correct Answer: C

Rationale: Administering 4 oz of orange juice is the appropriate action for a client experiencing hypoglycemia due to diabetes mellitus. Orange juice contains simple sugars that can quickly raise blood glucose levels. Insulin (Choice A) would further lower blood sugar, worsening the condition. Glucagon (Choice B) is used in severe hypoglycemia when the client cannot take anything by mouth. Administering 1 L of water (Choice D) is not indicated in hypoglycemia treatment; the priority is to raise blood sugar levels. Therefore, the correct choice is to administer orange juice to address the low blood sugar in this situation.

Correct Answer: A

Rationale: The correct nursing interventions for a patient with neutropenia include monitoring for signs of infection and administering antibiotics. Neutropenia is characterized by a low neutrophil count, which increases the risk of infections. Monitoring for signs of infection allows for early detection and prompt treatment, while administering antibiotics helps prevent or treat any infections that may occur. Isolating the patient and providing a low-microbial diet (Choice B) are not necessary unless the patient develops an active infection. Monitoring vital signs and avoiding unnecessary invasive procedures (Choice C) are important but do not specifically address the increased infection risk in neutropenic patients. Encouraging the patient to engage in social activities (Choice D) is not appropriate for a neutropenic patient due to the risk of exposure to infectious agents.

Correct Answer: C

Rationale: The correct answer is C: Obesity. Obesity is a significant risk factor for hypertension due to its impact on the cardiovascular system. Obesity can lead to increased blood pressure due to the additional workload placed on the heart and blood vessels. Age alone does not necessarily predispose someone to hypertension, and a family history of hypotension or a personal history of hypotension would not increase the risk of developing hypertension. Family history of hypotension is not a known risk factor for hypertension, and a history of hypotension actually indicates low blood pressure, which is the opposite of hypertension.
