1. The neurotransmitter GABA mainly functions to trigger inhibitory postsynaptic potentials (IPSPs). Therefore, when explaining this to a group of nursing students, the nurse will state:

Correct answer: C

Rationale: When GABA binds with a receptor site, it causes hyperpolarization of the local nerve membrane, making it less excitable. This hyperpolarization leads to inhibition of nerve cell activity. Choice A is incorrect because GABA is a neurotransmitter itself and does not require three chemical substances to stimulate activity between cells. Choice B is incorrect as GABA triggers inhibitory postsynaptic potentials (IPSPs), leading to hyperpolarization, not depolarization, of the postsynaptic membrane. Choice D is also incorrect as it describes a process involving cholinergic receptors and acetylcholine, which is unrelated to GABA's mechanism of action.

2. What key contraindication should the nurse emphasize to a patient prescribed sildenafil (Viagra) for erectile dysfunction?

Correct answer: A

Rationale: The correct answer is A. Sildenafil is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, leading to a synergistic effect that can result in a dangerous drop in blood pressure. Choices B, C, and D are incorrect because there is no specific contraindication for taking sildenafil with food, having a history of hypertension, or taking it with grapefruit juice. The main concern is the concurrent use of nitrates with sildenafil.

3. Listed below are five categories that identify the responsibilities of the practical nurse manager in personnel management. Which of these categories is most appropriate for the task 'Educate personnel on UCMJ'?

Correct answer: B

Rationale: The correct answer is B: Personal/professional development. Educating personnel on UCMJ falls under the category of personal/professional development as it involves enhancing their understanding of the Uniform Code of Military Justice. This category focuses on improving individuals' knowledge and skills related to their professional roles and responsibilities. Choices A, C, and D are not directly related to educating personnel on UCMJ. Accountability pertains to being answerable for one's actions, individual training focuses on specific skill development, and military appearance/physical condition relates to grooming standards and fitness rather than UCMJ education.

4. The nurse is reviewing the importance of role learning for children. The nurse understands that children's roles are primarily shaped by which members?

Correct answer: B

Rationale: Parents play the primary role in shaping their children's roles and behaviors, especially in early childhood, through modeling, guidance, and expectations.

5. Which of the following is a potassium-sparing diuretic?

Correct answer: B

Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.
