1. A male patient is receiving androgen therapy for hypogonadism. What laboratory tests should the nurse monitor during this therapy?

• A. Liver function tests
• B. Kidney function tests
• C. Prostate-specific antigen (PSA)
• D. Complete blood count (CBC)

Correct answer: A

Rationale: During androgen therapy for hypogonadism, it is important to monitor liver function tests. Androgens can affect the liver, potentially leading to liver dysfunction. Monitoring liver function tests helps in early detection of any liver abnormalities. Kidney function tests (Choice B) are not typically affected by androgen therapy. Prostate-specific antigen (PSA) levels (Choice C) may be monitored for conditions like prostate cancer, but it is not directly related to androgen therapy for hypogonadism. A complete blood count (CBC) (Choice D) may not show specific changes related to androgen therapy for hypogonadism.

2. When a healthcare professional observes muscle stiffening occurring within 6 to 14 hours after death, the healthcare professional should document this finding as _____ present.

• A. Livor mortis
• B. Gangrene
• C. Algor mortis
• D. Rigor mortis

Correct answer: D

Rationale: The correct answer is D, Rigor mortis. Rigor mortis is the stiffening of muscles after death, typically beginning within 6 to 14 hours. Livor mortis (choice A) refers to the pooling of blood in the lowest tissues causing discoloration, gangrene (choice B) is the death of body tissue due to lack of blood flow, and algor mortis (choice C) is the cooling of the body after death.

3. When reviewing the purpose/action of neurotransmitters as they interact with different receptors, the nursing instructor gives an example using acetylcholine. When acetylcholine is released at the sinoatrial node in the right atrium of the heart, it is:

• A. positively charged.
• B. inhibitory.
• C. overstimulated.
• D. dormant.

Correct answer: B

Rationale: Acetylcholine acts as an inhibitory neurotransmitter at the sinoatrial node. It slows down the heart rate by decreasing the firing rate of the sinoatrial node, which serves as the heart's natural pacemaker. Neurotransmitters do not have a charge, so choice A is incorrect. Choice C is wrong as overstimulation is not a characteristic of acetylcholine at the sinoatrial node. Choice D is also incorrect because acetylcholine actively influences heart rate regulation when released at the sinoatrial node.

4. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What is the expected therapeutic effect of this medication?

• A. Decreased urinary frequency and urgency
• B. Decreased blood pressure
• C. Increased urinary output
• D. Increased hair growth

Correct answer: A

Rationale: The correct answer is A: Decreased urinary frequency and urgency. Finasteride is used to reduce the size of the prostate gland in patients with BPH, which helps alleviate symptoms such as urinary frequency and urgency. Choice B, decreased blood pressure, is incorrect because finasteride is not indicated for lowering blood pressure. Choice C, increased urinary output, is incorrect as finasteride does not typically increase urine production. Choice D, increased hair growth, is incorrect as the primary use of finasteride is not for promoting hair growth but rather for treating BPH.

5. Which immunoglobulin presents the first challenge to the antigen?

• A. IgA
• B. IgG
• C. IgM
• D. IgE

Correct answer: C

Rationale: IgM is the first immunoglobulin to challenge the antigen during an immune response. IgM is the primary antibody produced during the initial or primary immune response. It is efficient in agglutination and complement activation, making it crucial in the early stages of defense. IgA is mainly found in mucosal areas and secretions. IgG is the most abundant antibody in circulation and is involved in secondary immune responses. IgE is primarily associated with allergic reactions and parasitic infections. Therefore, IgM is the correct choice as it acts first during the immune response, while the other immunoglobulins have different roles and functions.
