A nurse is developing a care plan for a client who has paraplegia and has an area of nonblanchable erythema over the ischium. Which intervention should the nurse include?

Correct Answer: B

Rationale: The correct intervention for a client with nonblanchable erythema over the ischium is to teach the client to shift his weight every 15 minutes while sitting. This action helps relieve pressure on the affected area and prevents further skin breakdown. Placing the client upright on a donut-shaped cushion (Choice A) may not address the need for frequent weight shifts. Turning and repositioning the client every 3 hours (Choice C) is important for overall skin health but may not provide adequate relief for the specific area of nonblanchable erythema. Assessing pressure points every 24 hours (Choice D) is not frequent enough to prevent worsening of the skin condition in this case.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT in patients receiving heparin therapy. Activated Partial Thromboplastin Time (aPTT) is crucial to assess the therapeutic effectiveness of heparin and to prevent bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy, not heparin. Platelet count (Choice C) monitoring is essential for detecting heparin-induced thrombocytopenia rather than assessing heparin therapy itself. Monitoring sodium levels (Choice D) is not directly related to heparin therapy monitoring.

Correct Answer: C

Rationale: The correct intervention for a client with deep vein thrombosis (DVT) is to elevate the affected extremity above the level of the heart. This position promotes venous return, reduces swelling, and helps prevent complications such as pulmonary embolism. Applying cold compresses (choice A) can vasoconstrict blood vessels, potentially worsening the condition. Massaging the affected extremity (choice B) can dislodge the clot and lead to serious complications. Keeping the affected extremity dependent when sitting (choice D) can hinder venous return and exacerbate the DVT.

Correct Answer: B

Rationale: Digoxin is commonly prescribed to manage atrial fibrillation by controlling heart rate. While Warfarin is used to prevent blood clots, it is not primarily used for controlling heart rate in atrial fibrillation. Aspirin is not the first-line treatment for atrial fibrillation and is generally not recommended for rhythm control. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure, but it is not typically prescribed as the primary medication for managing atrial fibrillation.

Correct Answer: B

Rationale: The correct answer is B: Absence of a bruit. In a client with an arteriovenous fistula, the presence of a bruit (a humming sound) is an expected finding due to the high-pressure flow of blood through the fistula. Therefore, the absence of a bruit suggests a complication, such as thrombosis or stenosis, which should be reported for further evaluation and management. Choices A, C, and D are incorrect because a thrill upon palpation, distended blood vessels, and a swishing sound upon auscultation are expected findings in a client with an arteriovenous fistula and do not necessarily indicate a complication.

Correct Answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

Correct Answer: B

Rationale: The correct answer is B. An apical pulse below 60/min indicates bradycardia, a potential sign of digoxin toxicity. The nurse should report this finding to the provider for further evaluation and possible adjustment of the digoxin dose. Choice A, a potassium level of 4.2 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not indicate toxicity. Choice C, a digoxin level of 1 ng/ml, is within the therapeutic range (0.5-2 ng/ml) and is not suggestive of toxicity. Choice D, constipation for 2 days, is not directly related to digoxin administration and would not require an immediate report to the provider.

Correct Answer: B

Rationale: The correct answer is B: Photosensitivity. Ciprofloxacin can cause photosensitivity, making the client more sensitive to sunlight. It is essential for the nurse to report this finding to the provider so that appropriate measures can be taken to prevent skin damage. Dry mouth, headache, and urinary retention are not typically associated with ciprofloxacin use and do not require immediate reporting to the provider in this scenario.

Correct Answer: C

Rationale: The correct answer is C. Increasing the intake of saturated fats can raise cholesterol levels, which is not recommended after a myocardial infarction. Choices A, B, and D are all appropriate statements indicating a good understanding of post-myocardial infarction care. Taking a daily aspirin can help prevent another heart attack, experiencing chest pain with exercise is a common expectation post-myocardial infarction, and participating in a cardiac rehabilitation program is important for recovery and improving heart health.
