A nurse is reviewing the allergies of a client who has rheumatoid arthritis prior to administering celecoxib to the client. The nurse should identify that which of the following allergies is a contraindication for receiving this medication?
- A. Sulfonamides
- B. Shellfish
- C. Fluoroquinolones
- D. Peanuts
Correct Answer: A
Rationale: The correct answer is A: Sulfonamides. Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) and belongs to the class of sulfonamides. Patients allergic to sulfonamides are at risk of cross-reactivity with celecoxib, leading to severe allergic reactions. Shellfish (B), fluoroquinolones (C), and peanuts (D) are not related to the mechanism of action or composition of celecoxib, so they are not contraindications. It is important for the nurse to identify sulfonamide allergies to prevent adverse reactions in patients receiving celecoxib.

A nurse is reviewing the medication list of a client who has a new prescription for tetracycline. The nurse should instruct the client to take which of the following medications 3 hr before or after taking the tetracycline?
- A. Hydrochlorothiazide
- B. Antacid
- C. Acetaminophen
- D. Lovastatin
Correct Answer: B
Rationale: The correct answer is B: Antacid. Tetracycline can bind to certain substances, like calcium in antacids, reducing its absorption. By taking the antacid 3 hours before or after tetracycline, the client can ensure optimal absorption of the antibiotic. Choice A, hydrochlorothiazide, does not interact significantly with tetracycline. Choices C and D also do not have significant interactions with tetracycline.
A nurse in a provider's office is collecting data from a client who continues to have a migraine headache after taking sumatriptan orally 2 hr ago. Which of the following findings is the priority for the nurse to report?
- A. Tingling sensation
- B. Hypertension
- C. Flushing
- D. Dizziness
Correct Answer: B
Rationale: The correct answer is B: Hypertension. The priority for the nurse to report is hypertension because sumatriptan can potentially cause an increase in blood pressure as a side effect. Hypertension is a serious condition that can lead to complications if not managed promptly.
A: Tingling sensation is a common side effect of sumatriptan and may not be immediately concerning.
C: Flushing is also a common side effect of sumatriptan and is usually not a priority.
D: Dizziness is a less severe side effect compared to hypertension and can often be managed with rest.
A nurse is reinforcing teaching with a newly licensed nurse about age-related changes that affect medication administration for older adult clients. Which of the following information should the nurse include?
- A. Hepatic enzymes process medications more rapidly.
- B. Gastric emptying rate increases.
- C. Brain receptors become less sensitive to medications.
- D. Renal excretion time slows for medication.
Correct Answer: D
Rationale: The correct answer is D: Renal excretion time slows for medication. As individuals age, there is a decline in renal function, leading to a decrease in glomerular filtration rate and renal blood flow. This results in a slower excretion of medications from the body, leading to potential accumulation and increased risk of toxicity. Choices A, B, and C are incorrect as hepatic enzymes may actually decrease in function with age, gastric emptying rate tends to slow down, and brain receptors can become more sensitive rather than less sensitive to medications in older adults.
A nurse is reviewing the medication administration record of a client who has an NG tube. Which of the following medications should the nurse plan to administer through the NG tube?
- A. Dipivefrin
- B. Salmeterol
- C. Lovastatin
- D. Nitroglycerin
Correct Answer: C
Rationale: The correct answer is C: Lovastatin. Lovastatin is a medication that can be administered through an NG tube as it is available in a liquid form suitable for tube administration. Dipivefrin (A) and Salmeterol (B) are not suitable for NG tube administration as they are ophthalmic and inhalation medications, respectively. Nitroglycerin (D) is typically given sublingually or transdermally for rapid effect, not via NG tube.
A nurse is collecting data from a client who takes furosemide daily for heart failure. Which of the following laboratory values should the nurse review before administering the medication?
- A. Erythrocyte sedimentation rate
- B. Thyroxine
- C. Serum potassium
- D. Serum aspartate aminotransferase
Correct Answer: C
Rationale: The correct answer is C: Serum potassium. Furosemide is a loop diuretic that can cause potassium depletion, leading to hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac arrhythmias. Erythrocyte sedimentation rate (A) is not relevant for assessing furosemide therapy. Thyroxine (B) is a thyroid hormone and not directly affected by furosemide. Serum aspartate aminotransferase (D) is a liver enzyme and not specifically impacted by furosemide administration.
