A healthcare provider is reviewing laboratory values for a client who reports fatigue and cold intolerance. The client has an increased thyroid-stimulating hormone (TSH) level and a decreased total T3 and T4 level. The healthcare provider should anticipate a prescription for which of the following medications?
- A. Methimazole
- B. Somatropin
- C. Levothyroxine
- D. Propylthiouracil
Correct Answer: C
Rationale: The client's symptoms and lab results indicate hypothyroidism, and levothyroxine is the standard treatment to replace the deficient thyroid hormones. Methimazole and propylthiouracil are used to treat hyperthyroidism by decreasing the production of thyroid hormones. Somatropin is a growth hormone used in conditions of growth hormone deficiency, not for hypothyroidism.

A healthcare professional is preparing to administer heparin 8,000 units subcutaneously every eight hrs. The amount available is heparin injection 10,000 units/mL. How many milliliters should the healthcare professional administer per dose?
- A. 0.7 mL
- B. 0.8 mL
- C. 1.0 mL
- D. 1.2 mL
Correct Answer: B
Rationale: Calculation: 8000 units / 10,000 units per mL = 0.8 mL. To correctly administer the prescribed dose of 8000 units, the healthcare professional should draw up 0.8 mL from the 10,000 units/mL vial. Options A, C, and D are incorrect as they do not accurately reflect the calculation based on the available concentration of heparin.
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.
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 nurse is preparing to administer an enteral tube feeding through an NG tube at 250 mL over 4 hr. The nurse should set the pump to deliver how many mL/hr?
- A. 60 mL/hr
- B. 62 mL/hr
- C. 63 mL/hr
- D. 65 mL/hr
Correct Answer: C
Rationale: Calculation: 250 mL / 4 hours = 62.5 mL/hr, which should be rounded up to 63 mL/hr. This ensures the correct rate is set for continuous feeding. Choice A (60 mL/hr) is incorrect as it does not reflect the accurate calculation. Choice B (62 mL/hr) is close but does not round up to the nearest whole number as required. Choice D (65 mL/hr) is higher than the correct calculation and would deliver the feeding solution at a faster rate than prescribed.
