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 A
Explanation
A. Heart rate of 56/min: Propranolol is a beta-blocker that can lower heart rate. A heart rate below 60/min may indicate bradycardia, which can be dangerous and requires intervention before administering the next dose.
B. SaO2 95% on 2 L/min of oxygen: Oxygen saturation of 95% on supplemental oxygen is within an acceptable range and does not require immediate intervention.
C. Blood pressure 106/68 mm Hg: While slightly on the lower side, this blood pressure is generally considered acceptable for many adults and does not typically necessitate an immediate intervention.
D. Respirations 22/min: A respiratory rate of 22/min is mildly elevated but usually not critical. It does not require withholding propranolol or immediate intervention in a stable client.
Correct Answer is A
Explanation
A. History of gastrointestinal bleeding: Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can inhibit prostaglandin synthesis, increasing the risk of gastrointestinal bleeding or ulceration. A history of GI bleeding is a contraindication due to the heightened risk of serious complications.
B. Liver impairment: While caution is warranted, mild to moderate liver impairment is not an absolute contraindication. Liver function should be monitored, but it does not automatically prevent ketorolac use.
C. Allergy to codeine: Ketorolac is not an opioid and does not contain codeine. An allergy to codeine does not contraindicate its administration.
D. History of glaucoma: Ketorolac does not typically affect intraocular pressure or exacerbate glaucoma. It is not contraindicated in clients with this condition.
