1. A client with cirrhosis is at risk for bleeding due to impaired liver function. Which laboratory result is the most important to monitor?
- A. Blood urea nitrogen (BUN)
- B. Prothrombin time (PT)
- C. Aspartate aminotransferase (AST)
- D. Serum albumin
Correct answer: B
Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.
2. In a client with chronic kidney disease having a serum potassium level of 6.5 mEq/L, which assessment is the most critical for the nurse to perform?
- A. Neurological status
- B. Cardiac status
- C. Respiratory status
- D. Gastrointestinal status
Correct answer: B
Rationale: Corrected Rationale: Assessing cardiac status is crucial in hyperkalemia as high potassium levels can result in life-threatening arrhythmias. Monitoring the heart rhythm and ECG findings is essential to prevent cardiac complications. Neurological status, respiratory status, and gastrointestinal status are important assessments too, but in the context of hyperkalemia, cardiac status takes precedence due to the immediate risk of cardiac arrhythmias.
3. The nurse is planning care for a client with a venous leg ulcer. Which intervention should the nurse include in the plan of care to promote healing?
- A. Apply compression therapy to the affected leg
- B. Keep the affected leg in a dependent position
- C. Massage the area surrounding the ulcer
- D. Encourage the client to elevate the leg for 2 hours daily
Correct answer: A
Rationale: Compression therapy is essential for managing venous leg ulcers as it helps improve venous return, reduces edema, and promotes healing. By applying compression therapy to the affected leg, the nurse can assist in enhancing circulation, reducing swelling, and aiding in the healing process. Keeping the affected leg in a dependent position can worsen venous insufficiency. Massaging the area surrounding the ulcer is contraindicated as it can cause further damage and delay healing. While encouraging the client to elevate the leg is beneficial, it is not as effective as compression therapy for promoting healing in venous leg ulcers.
4. A parent asks the school nurse how to eliminate lice from their child. What is the most appropriate response by the nurse?
- A. Cut the child's hair short to remove the nits
- B. Apply warm soaks to the head twice daily
- C. Wash the child's linen and clothing in a bleach solution
- D. Application of pediculicides
Correct answer: D
Rationale: Pediculicides are the recommended treatment for lice and should be used to eliminate the infestation.
5. A client has been taking isoniazid (INH) for 2 months. The client complains to a nurse about numbness, paresthesias, and tingling in the extremities. The nurse interprets that the client is experiencing:
- A. Hypercalcemia
- B. Peripheral neuritis
- C. Small blood vessel spasm
- D. Impaired peripheral circulation
Correct answer: B
Rationale: The client's symptoms of numbness, paresthesias, and tingling in the extremities indicate peripheral neuritis, a common side effect of isoniazid (INH). This condition can be managed by supplementing with pyridoxine (vitamin B6) to minimize the symptoms.
