Correct Answer: C

Rationale: When a client on heparin reports tarry stools, it can be indicative of gastrointestinal bleeding. The correct action for the nurse is to monitor the stools for blood and review the Partial Thromboplastin Time (PTT) results. This is essential to detect any potential bleeding complications associated with heparin therapy. Option A is incorrect because warfarin is not the immediate intervention for tarry stools in a client on heparin. Option B is irrelevant to the situation described. Option D is incorrect as Vitamin K is the antidote for warfarin, not heparin.

Correct Answer: D

Rationale: Purulent drainage suggests an infection at the wound site. Reviewing the culture and sensitivity results will guide appropriate antibiotic treatment by identifying the causative organisms and their antibiotic sensitivities. Elevated white blood cells indicate infection but do not specify the organism. Creatinine and hemoglobin values are unrelated to wound infections.

Correct Answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.

Correct Answer: A

Rationale: The correct answer is A: Administer furosemide as prescribed. Administering furosemide, a loop diuretic, is the priority intervention in a client with cirrhosis experiencing ascites and peripheral edema. Furosemide helps promote diuresis and reduce fluid buildup in the body. Choice B, administering albumin to increase oncotic pressure, may be beneficial in some cases but is not the priority intervention for immediate fluid removal. Elevating the client's legs (Choice C) and administering a sodium-restricted diet (Choice D) are important aspects of managing edema and ascites but are not the priority interventions in this situation.

Correct Answer: A

Rationale: The correct answer is A: 'Take the medication with a full glass of water.' It is crucial for the nurse to teach the client to take ciprofloxacin with a full glass of water to prevent crystalluria, a potential side effect of the medication. Choice B is incorrect because ciprofloxacin does not require avoiding direct sunlight. Choice C is incorrect as taking the medication with meals is not necessary to prevent nausea. Choice D is incorrect as dizziness is not a common reason to discontinue ciprofloxacin.
