HESI Medical Surgical Practice Exam Quizlet

Correct Answer: C

Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.

Correct Answer: D

Rationale: The correct answer is to restrict salt and fluid intake. In clients with cirrhosis presenting with pedal edema and ascites, excessive fluid retention occurs, necessitating the restriction of salt and fluid to alleviate these symptoms. Choice A, avoiding high carbohydrate foods, is not the priority in this situation. Decreasing intake of fat-soluble vitamins (Choice B) is not specifically indicated for managing edema and ascites in cirrhosis. While maintaining an appropriate caloric intake is important, decreasing caloric intake (Choice C) is not the primary focus when addressing fluid retention in cirrhosis.

Correct Answer: A

Rationale: In the scenario described, the client's presentation with bright-red blood vomiting after a tonsillectomy and adenoidectomy is highly concerning for an immediate postoperative hemorrhage, which can be life-threatening. The priority action for the nurse is to notify the surgeon immediately. Prompt communication with the surgeon is vital to ensure swift intervention and appropriate management to address the hemorrhage effectively. Continuing the assessment, checking the client's blood pressure, or obtaining equipment are all secondary actions in this critical situation and would delay the necessary urgent intervention required to manage the hemorrhage effectively.

Correct Answer: B

Rationale: The correct answer is B. The CDC guidelines recommend that healthcare workers wear gloves when coming in contact with blood or body fluids from any client since HIV can be infectious before the client becomes aware of their exposure and/or symptomatic. Choice A is incorrect because placing HIV-positive clients in strict isolation and limiting visitors is not a standard practice for HIV infection control. Choice C is incorrect as mandatory HIV testing for those working with AIDS clients is not a CDC recommendation for routine infection control. Choice D is incorrect because freezing HIV blood specimens at -70�F does not kill the virus; HIV can remain infectious even at very low temperatures.

Correct Answer: C

Rationale: The correct nursing intervention indicated based on the nursing diagnosis 'Potential for impairment of skin integrity related to immobility from traction' is to provide back and skin care while maintaining the traction. This intervention is crucial for maintaining the client's skin integrity and preventing potential complications. Releasing the traction every 4 hours (Choice A) may disrupt the treatment plan and compromise the effectiveness of traction. Turning the client for back care while suspending traction (Choice B) does not address the need for skin care while the client is in traction. Giving back care after the client is released from traction (Choice D) neglects the immediate need to prevent skin impairment while in traction. Therefore, providing back and skin care while maintaining the traction (Choice C) is the most appropriate intervention in this scenario.
