Fundamentals HESI

Correct Answer: B

Rationale: The correct answer is B: Crackles in the lungs. Crackles in the lungs indicate pulmonary congestion, a serious complication of left-sided heart failure. The presence of crackles suggests fluid accumulation in the lungs, impairing gas exchange and potentially leading to respiratory distress. Immediate intervention is necessary to prevent worsening respiratory function. Choices A, C, and D are incorrect: Peripheral edema is a common finding in heart failure but may not be as acutely concerning as pulmonary congestion. Jugular vein distention is associated with right-sided heart failure, not left-sided heart failure. Hepatomegaly is often seen in liver conditions and right-sided heart failure, not specifically left-sided heart failure.

Correct Answer: A

Rationale: The nurse should advise the client to document the exact medication taken to identify potential allergies and prevent adverse reactions. This is important as the client developed a rash previously while taking an antibiotic, indicating a possible allergic reaction. Choice B is not appropriate as switching antibiotics without proper evaluation can be risky. Choice C is incorrect as rashes should not be dismissed without further investigation, especially in the context of taking medication. Choice D is also not recommended as re-taking the same antibiotic without clarifying the allergic reaction can lead to a potentially severe outcome.

Correct Answer: A

Rationale: The correct answer is A because clients taking digoxin should avoid foods high in potassium. High potassium levels can potentiate the effects of digoxin, leading to toxicity. Choices B, C, and D are correct statements regarding digoxin administration. Checking the pulse before taking the medication helps monitor for signs of digoxin toxicity. Avoiding taking antacids simultaneously prevents interactions that may reduce digoxin absorption. Taking the medication at the same time every day helps maintain a consistent blood level, ensuring optimal therapeutic effects.

Correct Answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

Correct Answer: A

Rationale: The correct way to use a cane is for the client to hold it on the stronger side of the body. This positioning allows the cane to provide support to the weaker side, assisting with balance and stability. Placing the cane on the weaker side (Choice B) may not provide adequate support and could lead to an increased risk of falls. Holding the cane in front of the weaker side (Choice C) or in front of the stronger side (Choice D) does not optimize the support and stability needed while walking with a cane.
