A nurse is caring for a client who has a prescription for nifedipine. Which of the following findings should the nurse assess prior to administration of the medication?
Temperature
Respiratory rate
Blood pressure
Oxygen saturation
The Correct Answer is C
A. Temperature: Nifedipine does not directly affect body temperature, so assessing temperature is not critical prior to administration.
B. Respiratory rate: While monitoring respiratory status is important in general, nifedipine primarily affects the cardiovascular system, so respiratory rate is not the primary assessment focus.
C. Blood pressure: Nifedipine is a calcium channel blocker that lowers blood pressure by relaxing vascular smooth muscle. Assessing blood pressure before administration ensures the client is not hypotensive and helps prevent adverse cardiovascular effects.
D. Oxygen saturation: Oxygen saturation is not directly impacted by nifedipine, so it is not essential to assess this parameter prior to giving the medication.

Correct Answer is C
Explanation
A. "I know I will need to take methimazole for the rest of my life.": Methimazole therapy is often temporary, used to control hyperthyroidism until definitive treatment or remission occurs. Lifelong use is not necessarily required.
B. "I should take methimazole 1 hr before eating.": Methimazole can be taken with or without food. Timing relative to meals is not critical for its absorption, so taking it strictly one hour before eating is unnecessary.
C. "I should be vigilant with birth control while taking methimazole.": Methimazole can be teratogenic, especially during the first trimester of pregnancy. Effective contraception is important to prevent fetal harm while on this medication.
D. "I should stop taking methimazole when my night sweats go away.": Symptoms may improve before thyroid hormone levels normalize. Stopping methimazole prematurely can lead to relapse of hyperthyroidism, so discontinuation should only occur under provider guidance.
Correct Answer is A
Explanation
A. Dual-energy x-ray absorptiometry (Dexa scan): Dexa scans measure bone mineral density and are the standard tool for diagnosing osteoporosis and monitoring the effectiveness of treatments like alendronate. Changes in bone density over time indicate how well the medication is working.
B. Urine specific gravity: This test evaluates kidney function and hydration status but does not provide information about bone density or the effectiveness of osteoporosis therapy.
C. Lumbar puncture: A lumbar puncture assesses cerebrospinal fluid for neurological conditions. It has no role in evaluating osteoporosis treatment or bone health.
D. Hemoglobin A1C (Hb A1C): HbA1C measures average blood glucose over several months, used in diabetes management. It does not reflect changes in bone density or the impact of alendronate therapy.
