1. When a healthcare professional is reviewing lab results and notices that the erythrocytes contain an abnormally low concentration of hemoglobin, the healthcare professional calls these erythrocytes:

Correct answer: B

Rationale: Erythrocytes with an abnormally low concentration of hemoglobin are called hypochromic. Hyperchromic refers to erythrocytes with an abnormally high concentration of hemoglobin. Macrocytic indicates larger than normal red blood cells, while microcytic refers to smaller than normal red blood cells. Therefore, in this scenario, the correct term is hypochromic.

2. A patient is found to have liver disease, resulting in the removal of a lobe of his liver. Adaptation to the reduced size of the liver leads to ___________ of the remaining liver cells.

Correct answer: C

Rationale: Compensatory hyperplasia is the process by which the remaining cells increase in number to adapt to the reduced size of the liver. In this case, after the removal of a lobe of the liver, the remaining cells undergo compensatory hyperplasia to compensate for the lost tissue. Metaplasia refers to the reversible change of one cell type to another, not an increase in cell number. Organ atrophy is the decrease in organ size due to cell shrinkage or loss, which is opposite to an increase in cell number seen in compensatory hyperplasia. Physiologic hyperplasia is the increase in cell number in response to a normal physiological demand, not specifically due to the removal of a portion of the organ.

3. A patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What outcome should the nurse expect to observe if the medication is effective?

Correct answer: B

Rationale: The correct answer is B: Decreased prostate size. Finasteride is a medication used to reduce the size of the prostate gland in patients with BPH. By decreasing the size of the prostate, symptoms such as urinary frequency and urgency are improved. Choice A is incorrect as the medication aims to decrease, not increase, urinary symptoms. Choice C is incorrect because the goal of finasteride is to reduce, not increase, the prostate size. Choice D is also incorrect as finasteride is not indicated for lowering blood pressure.

4. When administering azoles in the home setting, the home health nurse should prioritize educational interventions that address what nursing diagnosis?

Correct answer: A

Rationale: The correct answer is A: Risk for injury related to antifungal therapy. When administering azoles, the priority is to educate patients and caregivers about potential side effects that could lead to injury, such as hepatotoxicity or allergic reactions. Choices B, C, and D are incorrect because acute confusion, infection, and falls are not typically associated with azole therapy.

5. During a late-night study session, a pathophysiology student reaches out to turn the page of her textbook. Which component of her nervous system contains the highest level of control of her arm and hand action?

Correct answer: A

Rationale: The correct answer is A: Cerebral cortex. The cerebral cortex, particularly the motor cortex, is responsible for the voluntary control of precise movements such as turning a page. The cerebral cortex plays a crucial role in the highest level of control of motor functions, including those of the arm and hand. Choice B, Basal ganglia, is more involved in motor planning and coordination, while choice C, Brainstem, is responsible for basic life functions and reflexes. Choice D, Cerebellum, is primarily involved in coordination, precision, and accurate timing of movements, rather than the highest level of control for specific actions like page-turning.
