HESI Medical Surgical Practice Quiz

Correct Answer: C

Rationale: Gentamicin peak levels should ideally be between 5 to 8 mcg/mL, and trough levels should be within the range of 0.5 to 2 mcg/mL to ensure therapeutic efficacy while minimizing toxicity risk. In this case, the patient's peak level is above the recommended range, and the trough level is at the higher end, indicating potential drug toxicity. Therefore, the correct action for the healthcare professional is to report the possibility of drug toxicity to the patient's healthcare provider. Administering the next dose as prescribed (Choice A) would exacerbate the toxicity risk. Obtaining repeat peak and trough levels (Choice B) may confirm the current levels but does not address the immediate concern of potential toxicity. Reporting a decreased drug therapeutic level (Choice D) is not the priority in this scenario, as the focus should be on addressing the potential toxicity issue.

Correct Answer: D

Rationale: The correct action for the nurse to take in this situation is to assess the client's abdomen and vital signs. The nephrostomy tube should have a consistent amount of drainage, and a decrease may indicate obstruction. Before notifying the provider, the nurse must assess the client for pain, distention, and changes in vital signs. This assessment is crucial to gather essential information to report accurately. Documenting the finding without further assessment may delay necessary intervention. Evaluating the tube as working in the hand-off report or clamping the tube prematurely are not appropriate actions and could lead to complications if there is an obstruction.

Correct Answer: A

Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client's health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client's blood glucose, and administering intravenous fluids should be part of the client's plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.

Correct Answer: A

Rationale: When erythromycin and cefaclor are taken together, erythromycin can inhibit the metabolism of cefaclor, leading to elevated cefaclor levels and potentially causing adverse effects. This results in a decrease in the effectiveness of cefaclor. Therefore, the nurse should discuss this potential drug interaction with the provider to consider an alternative treatment or adjust the dosages to prevent complications. Choices B, C, and D are incorrect because the concern lies with the effect on cefaclor when combined with erythromycin, not the effect on erythromycin itself.

Correct Answer: D

Rationale: The correct answer is D, Tetracycline (Sumycin). Tetracyclines should not be given to children younger than 8 years of age because they irreversibly discolor the permanent teeth. Azithromycin, Clarithromycin, and Clindamycin are antibiotics that are generally safe for use in children and do not have the same tooth discoloration side effect as Tetracycline. Therefore, these antibiotics would be more appropriate choices for a 7-year-old patient.
