Correct Answer: C

Rationale: The correct answer is C: Hemoglobin level. Erythropoietin therapy is used to stimulate red blood cell production in patients with chronic kidney disease who often develop anemia due to reduced erythropoietin production by the kidneys. Monitoring the hemoglobin level is essential to evaluate the effectiveness of erythropoietin therapy as an increase in hemoglobin indicates improved red blood cell production and better management of anemia in these patients. Serum creatinine, white blood cell count, and serum potassium levels are important parameters to monitor in CKD patients but are not specific indicators of the effectiveness of erythropoietin therapy for managing anemia.

Correct Answer: B

Rationale: The correct instruction for a patient with hypothyroidism prescribed levothyroxine is to take the medication in the morning on an empty stomach to enhance absorption. Taking it with meals can interfere with absorption. Patients should not discontinue the medication without consulting their healthcare provider as it can lead to adverse effects. Doubling the dose if a dose is missed can increase the risk of side effects and overdosage. It is crucial for patients to follow the prescribed dosing schedule and consult their healthcare provider for any concerns or missed doses.

Correct Answer: C

Rationale: Although presymptomatic testing for genetic disorders allows patients to take action (such as mastectomy) to prevent the development of some genetically caused disorders, patients also need to consider that test results in their medical record may affect insurance, employability, etc. Telling a patient that a decision about mastectomy should be made before testing implies that the nurse has made a judgment about what the patient should do if the test is positive. Although most breast cancers are not related to BRCA gene mutations, the patient with a BRCA gene mutation has a markedly increased risk for breast cancer.

Correct Answer: A

Rationale: Hepatic encephalopathy is the most likely condition causing confusion and disorientation in a client with liver cirrhosis. This condition is a common complication of liver cirrhosis and is characterized by cognitive impairment due to elevated ammonia levels in the blood. The build-up of ammonia affects brain function, leading to symptoms such as confusion, disorientation, and altered consciousness.

Correct Answer: B

Rationale: The most important instruction to give to a patient using a corticosteroid inhaler is to rinse the mouth after each use. This is crucial to prevent the development of oral thrush, a common side effect of corticosteroid inhalers. Failure to rinse the mouth can lead to the overgrowth of yeast in the mouth, causing oral thrush, which can be uncomfortable and require additional treatment. Therefore, reminding patients to rinse their mouth after using the inhaler is essential in preventing this potential complication.
