Nursing Elites

1. A 67-year-old man is receiving androgen therapy for osteoporosis. What laboratory test should the nurse monitor during this therapy?

• A. Liver function tests
• B. Blood glucose levels
• C. Prostate-specific antigen (PSA)
• D. Cholesterol levels

Correct answer: A

Rationale: During androgen therapy, monitoring liver function tests is crucial to detect any signs of liver dysfunction. Androgens can potentially impact liver function, making it essential to monitor enzymes such as ALT and AST. While blood glucose levels and cholesterol levels are important parameters to monitor in certain situations, they are not the primary focus during androgen therapy for osteoporosis. Prostate-specific antigen (PSA) monitoring is more relevant in the context of prostate health and cancer screening, not specifically during androgen therapy for osteoporosis.

2. A client asks a nurse about the cause of Parkinson's disease. How should the nurse respond?

• A. Parkinson's disease is caused by a lack of dopamine in the brain, which affects movement.
• B. Parkinson's disease is caused by an excess of acetylcholine in the brain, leading to tremors and rigidity.
• C. Parkinson's disease is caused by an autoimmune response that attacks the nervous system.
• D. Parkinson's disease is caused by a bacterial infection that needs to be treated with antibiotics.

Correct answer: A

Rationale: The correct answer is A. Parkinson's disease is caused by a deficiency of dopamine in the brain, which results in the characteristic motor symptoms such as tremors, rigidity, and bradykinesia. Choice B is incorrect because Parkinson's disease is not caused by an excess of acetylcholine. Choice C is incorrect because Parkinson's disease is not an autoimmune disorder. Choice D is incorrect because Parkinson's disease is not caused by a bacterial infection and cannot be treated with antibiotics.

3. What part of the heart is responsible for starting the electrical impulse to conduct a heart rhythm and contraction of the atria and ventricles?

• A. The Purkinje fibers in the ventricles
• B. The right & left bundle branches
• C. The atrioventricular node
• D. The sinoatrial node in the atrium

Correct answer: D

Rationale: The sinoatrial node (SA node) in the atrium is indeed responsible for initiating the electrical impulse that starts the heart's rhythm. The SA node is known as the heart's natural pacemaker. Choices A, B, and C are incorrect because while the Purkinje fibers, bundle branches, and atrioventricular node play crucial roles in the conduction of the electrical impulse throughout the heart, the SA node is specifically responsible for initiating this impulse.

4. A patient is administered a nucleotide reverse transcriptase inhibitor in combination with a nonnucleotide reverse transcriptase inhibitor. What is the main rationale for administering these medications together?

• A. They improve treatment adherence.
• B. They reduce the duration of illness.
• C. They exhibit synergistic antiviral effects.
• D. They prevent opportunistic infections.

Correct answer: C

Rationale: The main rationale for administering a nucleotide reverse transcriptase inhibitor in combination with a nonnucleotide reverse transcriptase inhibitor is that they exhibit synergistic antiviral effects when used together. This combination enhances their antiviral activity against HIV by targeting different steps in the viral replication cycle. Choice A is incorrect because the rationale for combining these medications is based on their antiviral effects, not treatment adherence. Choice B is incorrect because the primary purpose of combination therapy is not to reduce the duration of illness but to improve treatment efficacy. Choice D is incorrect as the main focus of this combination is not on preventing opportunistic infections but on directly targeting the HIV virus.

5. In a male patient with benign prostatic hyperplasia (BPH) prescribed tamsulosin (Flomax), what is the expected therapeutic effect of this medication?

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

Correct answer: A

Rationale: The correct answer is A: Decreased urinary frequency and urgency. Tamsulosin is prescribed for patients with BPH to relax the muscles in the prostate and bladder neck. This relaxation helps in relieving the symptoms of BPH, such as decreased urinary flow, frequent urination, and urgency. Choice B is incorrect because tamsulosin does not increase urinary output but rather improves the flow of urine by relaxing the muscles. Choice C is incorrect as tamsulosin is not primarily used for reducing blood pressure. Choice D is also incorrect as tamsulosin does not promote increased hair growth.
