A nurse in an outpatient facility is assessing a client who is prescribed furosemide 40 mg daily, but the client reports she has been taking extra doses to promote weight loss. Which of the following findings indicates she is dehydrated?
- A. Urine specific gravity of 1.020
- B. Urine specific gravity of 1.035
- C. Decreased skin turgor
- D. Decreased heart rate
Correct Answer: B
Rationale: The correct answer is B. A urine specific gravity greater than 1.030 is indicative of dehydration as it reflects concentrated urine. Choice A is incorrect as a specific gravity of 1.020 is within the normal range. Choice C, decreased skin turgor, can be a sign of dehydration but is not as specific as urine specific gravity. Choice D, decreased heart rate, is not typically a direct indicator of dehydration.

A nurse is preparing to administer ampicillin 500 mg in 50 mL of dextrose 5% in water (D5W) to infuse over 15 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver?
- A. 30 gtt/min
- B. 32 gtt/min
- C. 33 gtt/min
- D. 35 gtt/min
Correct Answer: C
Rationale: Calculation: 10 gtt/mL 50 mL · 15 min = 33.33, rounded to 33 gtt/min. This ensures proper delivery of the medication over the prescribed time. Choice A is incorrect because it does not factor in the precise calculation based on the given data. Choice B is incorrect as it does not reflect the accurate rate of infusion required. Choice D is incorrect as it does not align with the correct calculation based on the drop factor and infusion parameters provided in the question.
A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include a severe allergy to which of the following medications as a contraindication to ceftriaxone?
- A. Gentamicin
- B. Clindamycin
- C. Piperacillin
- D. Sulfamethoxazole-trimethoprim
Correct Answer: C
Rationale: Ceftriaxone is a cephalosporin, and individuals with a penicillin allergy (such as Piperacillin) may have cross-sensitivity, making it contraindicated. Gentamicin (Choice A) belongs to the aminoglycoside class, not related to cephalosporins. Clindamycin (Choice B) is a lincosamide antibiotic and is not typically associated with cross-allergies to cephalosporins. Sulfamethoxazole-trimethoprim (Choice D) is a sulfonamide antibiotic, also not directly related to ceftriaxone.
A client at 28 weeks of gestation is experiencing preterm labor. Which of the following medications should the nurse plan to administer?
- A. Oxytocin
- B. Nifedipine
- C. Dinoprostone
- D. Misoprostol
Correct Answer: B
Rationale: Nifedipine is the correct choice in this scenario. It is a calcium channel blocker that helps suppress uterine contractions and halt preterm labor. Nifedipine is commonly used to manage preterm labor in pregnant women by relaxing the smooth muscle of the uterus. Oxytocin (Choice A) is used to induce or augment labor, not to inhibit contractions. Dinoprostone (Choice C) and Misoprostol (Choice D) are prostaglandins used for cervical ripening and induction of labor, not for stopping preterm labor.
A nurse is caring for a client who has congestive heart failure and is taking digoxin. The client reports nausea and refuses to eat breakfast. Which of the following actions should the nurse take first?
- A. Encourage the client to eat the toast on the breakfast tray
- B. Administer an antiemetic
- C. Inform the client's provider
- D. Check the client's apical pulse
Correct Answer: D
Rationale: The correct answer is to check the client's apical pulse first. Nausea can be a sign of digoxin toxicity, and assessing the client's heart rate is crucial in this situation. Administering an antiemetic or encouraging the client to eat should come after ensuring the client's safety. While informing the provider is important, the immediate concern is to assess for potential digoxin toxicity by checking the client's apical pulse.
A nurse is planning to administer diltiazem via IV bolus to a client who has atrial fibrillation. Which of the following findings is a contraindication to the administration of diltiazem?
- A. Hypotension
- B. Tachycardia
- C. Decreased level of consciousness
- D. History of diuretic use
Correct Answer: A
Rationale: The correct answer is A: Hypotension. Diltiazem, a calcium channel blocker, can cause hypotension. Administering diltiazem to a client with hypotension can further lower their blood pressure, leading to adverse effects like dizziness and syncope. Tachycardia (Choice B) is actually a common indication for diltiazem use, as it helps slow down the heart rate in conditions like atrial fibrillation. Decreased level of consciousness (Choice C) may require evaluation but is not a direct contraindication to diltiazem administration. History of diuretic use (Choice D) is not a contraindication to diltiazem, as the two medications can often be safely used together.
