A healthcare provider is assessing a client who is receiving IV gentamicin three times daily. Which of the following findings indicates that the client is experiencing an adverse effect of this medication?
- A. Hypoglycemia
- B. Proteinuria
- C. Nasal congestion
- D. Visual disturbances
Correct Answer: B
Rationale: Corrected Rationale: Gentamicin is known to cause nephrotoxicity as an adverse effect. Proteinuria, which is the presence of excess proteins in the urine, may indicate kidney damage from the medication. Monitoring renal function is crucial in clients receiving gentamicin. Choice A, hypoglycemia, is not a typical adverse effect of gentamicin. Choices C and D, nasal congestion and visual disturbances, are not commonly associated with gentamicin use or its adverse effects.

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 indicates she is dehydrated?
- A. Urine specific gravity of 1.035
- B. Oliguria, increased urine concentration, and an increase in urine specific gravity greater than 1.030
- C. Polyuria
- D. Hypotension
Correct Answer: B
Rationale: Oliguria (reduced urine output), increased urine concentration, and a urine specific gravity greater than 1.030 are indicative of dehydration, particularly in clients using diuretics excessively. Choice A is incorrect because a urine specific gravity of 1.035 is high, indicating concentrated urine but not specifically dehydration. Choice C, polyuria, refers to increased urine output and is not consistent with dehydration. Choice D, hypotension, is a sign of fluid volume deficit but is not specific to dehydration as described in the scenario.
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 preparing to administer furosemide 4 mg/kg/day PO divided into 2 equal doses daily to a toddler who weighs 22 lb. How many mg should the nurse administer per dose?
- A. 10 mg
- B. 20 mg
- C. 30 mg
- D. 40 mg
Correct Answer: B
Rationale: To calculate the correct dose, first, convert the toddler's weight from pounds to kilograms: 22 lb / 2.2 lb/kg = 10 kg. Next, multiply the weight in kilograms by the dosage: 4 mg/kg x 10 kg = 40 mg/day. Since the total daily dose is divided into 2 equal doses, each dose would be 20 mg. Therefore, the correct answer is 20 mg. Choice A (10 mg) is incorrect because it does not account for the correct weight-based dosage. Choice C (30 mg) and Choice D (40 mg) are incorrect as they do not correctly calculate the dose based on the weight of the toddler and the prescribed dosage per kg.
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.
