Evolve HESI Medical Surgical Practice Exam

Correct Answer: D

Rationale: The correct interventions to promote kidney health in an older adult client include ensuring adequate fluid intake to maintain hydration and leaving the bathroom light on at night to promote safe ambulation. Adequate hydration supports kidney function and helps prevent urinary tract infections. Encouraging the use of the toilet every 6 hours is not specific to kidney health and may not be individualized to the client's needs. Providing thorough perineal care after each voiding is important for hygiene but not directly related to promoting kidney health. Assessing for urinary retention and urinary tract infections is crucial but falls under assessment rather than interventions for promoting kidney health specifically.

Correct Answer: A

Rationale: To calculate the rate of the intravenous pump, divide the total volume of fluid (3 L = 3000 mL) by the total time in hours (6 hours), which equals 500 mL/hr. The correct answer is A. Choice B (400 mL/hr) is incorrect as it would result in a slower infusion rate. Choice C (550 mL/hr) and Choice D (600 mL/hr) are incorrect as they would result in a faster infusion rate, exceeding the prescribed amount of fluid to be infused over 6 hours.

Correct Answer: A

Rationale: After checking the residual feeding contents, the nurse should pour the residual volume back into the stomach by removing the syringe bulb or plunger and then pouring the gastric contents, using the syringe, into the nasogastric tube. This helps ensure that the residual volume is reintroduced into the client's gastrointestinal tract. Option B is incorrect because discarding the residual volume without reinstilling it into the stomach can lead to inaccurate medication administration and potential electrolyte imbalances. Option C is incorrect as diluting the residual volume with water and injecting it under pressure can cause aspiration or discomfort for the client. Option D is incorrect because mixing the residual volume with the formula can alter the prescribed dosage and consistency, potentially affecting the client's nutritional intake and causing complications.

Correct Answer: C

Rationale: The correct answer is C. The absence of cough and gag reflexes is the most concerning finding for the nurse because it indicates a lack of protective airway reflexes, putting the client at risk of aspiration. Oxygen saturation of 97% is within the normal range and indicates adequate oxygenation. Equal breath sounds in both lungs are a positive finding, indicating no significant abnormalities. A respiratory rate of 20 breaths/min is also within the normal range and does not raise immediate concerns. Therefore, the absence of cough and gag reflexes poses the highest risk to the client's airway safety.

Correct Answer: D

Rationale: The most crucial action before administering an antibiotic for a urinary tract infection is to obtain a specimen for culture and sensitivity. This ensures the accurate identification of the causative organism and helps determine the most effective antibiotic therapy. Administering a test dose to detect hypersensitivity is usually reserved for cases with a strong suspicion of allergy to a needed antibiotic. Keeping epinephrine available is important when there is a significant risk of a severe allergic reaction. Monitoring baseline vital signs is essential during antibiotic therapy but is not the top priority before administering the first dose.
