A nurse is caring for a 62-year-old female client on a medical-surgical unit.

The Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"B"}
The client is at risk for hypotension due to hydrochlorothiazide.
Rationale for correct answers: Hydrochlorothiazide is a thiazide diuretic that reduces blood volume by promoting renal excretion of sodium and water, which lowers blood pressure. This mechanism can lead to hypotension, especially in postoperative patients with fluid shifts or concurrent antihypertensive therapy. Normal blood pressure is approximately 120/80 mm Hg, and this client’s current blood pressure of 92/75 mm Hg indicates mild hypotension, likely related to the diuretic effect of hydrochlorothiazide.
Rationale for incorrect Response 1 options:
Hypoglycemia is a low blood glucose state (below 70 mg/dL) often caused by excess insulin or insufficient food intake, but hydrochlorothiazide typically does not cause hypoglycemia. Instead, it can sometimes increase glucose levels due to altered insulin sensitivity. Hyperkalemia (elevated potassium >5.0 mEq/L) is unlikely because thiazides promote potassium excretion, tending toward hypokalemia rather than hyperkalemia. Infection risk is unrelated to hydrochlorothiazide use and would be influenced more by surgery or immune status.
Rationale for incorrect Response 2 options:
Insulin glargine is a long-acting insulin primarily influencing blood glucose, not blood pressure. Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can cause renal impairment and fluid retention but does not directly cause hypotension. Glucose level is a lab value, not a medication or intervention that causes hypotension.
Take home points:
- Hydrochlorothiazide can cause hypotension through volume depletion and natriuresis.
- Blood pressure monitoring is essential in postoperative patients on diuretics.
- Differentiate drug-induced hypotension from other causes such as bleeding or sepsis.
- Understand that thiazides can increase blood glucose and decrease potassium levels, influencing diabetic management.

Correct Answer is A
Explanation
Choice A rationale
Somatropin is a synthetic growth hormone used to treat growth hormone deficiency. The primary therapeutic effect of this medication is to promote linear growth in children. Therefore, monitoring the child's height monthly is a direct and quantifiable measure to evaluate the effectiveness of somatropin therapy and ensure that the child is achieving the expected growth velocity.
Choice B rationale
While thyroid function can influence growth, and growth hormone deficiency can sometimes coexist with or impact thyroid axis, evaluating the therapeutic effect of somatropin directly involves assessing growth. Monitoring thyroid function is important for overall endocrine health but is not the primary measure for the therapeutic effect of somatropin itself, assuming thyroid function is within normal limits (e.g., TSH 0.4-4.0 mIU/L, free T4 0.8-1.8 ng/dL).
Choice C rationale
Checking the child's sodium level regularly is not a direct measure of the therapeutic effect of somatropin. Growth hormone can influence fluid balance, but sodium levels (normal range 135-145 mEq/L) are primarily monitored for hydration status or potential adverse effects like fluid retention, not as an indicator of growth hormone's efficacy in promoting growth.
Choice D rationale
Measuring the child's abdominal girth is a measure of abdominal circumference, primarily used to assess abdominal distention, fluid accumulation, or changes in visceral fat. It is not a relevant parameter for evaluating the therapeutic effect of somatropin, which is specifically aimed at stimulating linear bone growth and overall somatic growth.
Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"D"}
Explanation
The client is at risk for developing hallucinations and weight loss.
Rationale for correct answers:
Bupropion is an atypical antidepressant used for smoking cessation that acts by inhibiting the reuptake of norepinephrine and dopamine. It is known to potentially cause neuropsychiatric side effects, including hallucinations, especially in patients with a history of psychiatric disorders such as bipolar disorder. Weight loss is a common adverse effect due to bupropion’s appetite suppression and increased metabolism. Normal weight is assessed by BMI, and this client has a normal BMI, but bupropion may exacerbate weight loss. Hallucinations indicate serious CNS involvement and require close monitoring.
Rationale for incorrect Response 1 options:
Dependence is not typically associated with bupropion; it has a low abuse potential. Somnolence or drowsiness is not a prominent side effect; bupropion is generally stimulating rather than sedating. Hypotension is also not a common effect; bupropion may actually increase heart rate and blood pressure slightly.
Rationale for incorrect Response 2 options:
Somnolence is not common; patients may experience insomnia rather than sedation. Hallucinations are already selected as a correct response. Hypotension is rare; instead, bupropion can cause hypertension in some cases. Weight loss is a known side effect and thus the correct choice.
Take home points:
- Bupropion can cause neuropsychiatric side effects, especially in clients with bipolar disorder.
- Weight loss may occur due to appetite suppression and increased metabolism.
- Monitor closely for CNS symptoms such as hallucinations during therapy.
- Smoking cessation pharmacotherapy must be tailored considering psychiatric history to avoid adverse effects.
