HESI RN CAT Exam Quizlet

Correct Answer: D

Rationale: In cardiogenic shock, the priority nursing diagnosis is Ineffective Tissue Perfusion. This diagnosis indicates that the client is not receiving adequate oxygenated blood to tissues, putting vital organs at risk. Addressing ineffective tissue perfusion is crucial to prevent organ damage and ensure the client's survival. The other options, such as 'Risk for imbalanced body temperature,' 'Excess fluid volume,' and 'Fatigue,' are important but secondary to the immediate threat of inadequate tissue perfusion in cardiogenic shock.

Correct Answer: D

Rationale: Tomatoes and lettuce are high in vitamin C, making them suitable choices for a diet prescribed for wound healing. Bananas and pineapple (Choice A) are not particularly high in vitamin C compared to tomatoes and lettuce. Cottage cheese and crackers (Choice B) as well as peanut butter and jelly (Choice C) do not provide significant amounts of vitamin C, which is essential for wound healing.

Correct Answer: B

Rationale: Offering blood pressure screening and monitoring is crucial for young adults as it helps in the early detection and management of hypertension, a condition that often goes unnoticed. High blood pressure can lead to serious health issues if left untreated. While education on smoking cessation, safe sex practices, healthy diet, and exercise are important aspects of overall health promotion, blood pressure screening takes precedence due to its immediate impact on health and the prevention of potential complications.

Correct Answer: B

Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.

Correct Answer: C

Rationale: The correct answer is to aspirate for blood return before injecting. This action helps ensure that the needle is not in a blood vessel, reducing the risk of injury. Using a 1-inch needle (Choice A) is a standard length for intramuscular injections but does not directly reduce the risk of injury. Selecting a large muscle for the injection (Choice B) is important for proper medication absorption but does not directly reduce the risk of injury. Massaging the injection site (Choice D) can help with medication absorption but does not reduce the risk of injury.
