1. While performing a skin inspection for a female adult client, the nurse observes a rash that is well circumscribed, has silvery scales and plaques, and is located on the elbows and knees. These assessment findings are likely to indicate which condition?

A. Tinea corporis
B. Herpes zoster
C. Psoriasis
D. Drug reaction

Correct answer: C

Rationale: The correct answer is C, Psoriasis. Psoriasis commonly presents with well-circumscribed, silvery scales and plaques, typically found on extensor surfaces like elbows and knees. Tinea corporis (A) presents as a circular rash, herpes zoster (B) presents as a painful rash following a dermatomal pattern, and drug reactions (D) have variable presentations not specific to elbows and knees with silvery scales and plaques.

2. An adult female client is admitted to the psychiatric unit because of a complex handwashing ritual she performs daily that takes two hours or longer to complete. She worries about staying clean and refuses to sit on any of the chairs in the day area. This client's handwashing is an example of which clinical behavior?

A. Addiction
B. Phobia
C. Compulsion
D. Obsession

Correct answer: C

Rationale: The client’s handwashing ritual is a compulsion, a repetitive behavior driven by the need to reduce anxiety associated with an obsession. In this case, the client's need to wash her hands excessively stems from an obsession with cleanliness, leading to the compulsive behavior of extensive handwashing. 'Addiction' (Choice A) involves a dependence on a substance or behavior, not related to this scenario. 'Phobia' (Choice B) is an intense fear of a specific object or situation, not applicable here. 'Obsession' (Choice D) refers to persistent and intrusive thoughts, while the handwashing behavior in this case is the compulsive action taken to alleviate the anxiety related to the obsession.

3. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

A. Serum potassium level
B. Hemoglobin level
C. White blood cell count
D. Serum calcium level

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. When a client with chronic kidney disease (CKD) is receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can stimulate red blood cell production, leading to an increased demand for potassium. This increases the risk of hyperkalemia, making it crucial to monitor potassium levels closely. Choices B, C, and D are incorrect because erythropoietin therapy primarily affects red blood cell production, not hemoglobin, white blood cell count, or serum calcium levels.

4. A 59-year-old male client comes to the clinic and reports his concern over a lump that 'just popped up on my neck about a week ago.' In performing an examination of the lump, the nurse palpates a large, nontender, hardened left subclavian lymph node. There is no overlying tissue inflammation. What do these findings suggest?

A. Malignancy
B. Infection
C. Benign cyst
D. Lymphadenitis

Correct answer: A

Rationale: The correct answer is A: Malignancy. A large, non-tender, hardened lymph node is a typical sign of malignancy and warrants further investigation. Choice B (Infection) is incorrect because typically in infections, lymph nodes are tender and may show signs of inflammation. Choice C (Benign cyst) is incorrect as a benign cyst would usually present as a soft, mobile lump. Choice D (Lymphadenitis) is incorrect as lymphadenitis usually presents with tender and enlarged lymph nodes due to inflammation.

5. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value is most concerning?

A. INR of 3.0
B. Prothrombin time (PT) of 15 seconds
C. Hemoglobin of 10 g/dl
D. White blood cell count

Correct answer: A

Rationale: An INR of 3.0 is most concerning in a client prescribed warfarin (Coumadin) as it indicates a high risk of bleeding, requiring immediate intervention. A high INR value suggests that the blood is taking longer to clot, putting the patient at an increased risk of hemorrhage. Prothrombin time (PT) measures how long it takes for blood to clot, but the specific value of 15 seconds is within the normal range. Hemoglobin of 10 g/dl indicates mild anemia and does not directly relate to the risk of bleeding associated with warfarin therapy. White blood cell count assesses immune function and infection risk, but it is not directly related to the anticoagulant effects of warfarin.
