Nursing Elites

1. 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.

2. When administering an immunization, which of the following medications should be available?

• A. Diphenhydramine (Benadryl)
• B. Hydroxyzine (Vistaril)
• C. Physostigmine
• D. Epinephrine

Correct answer: D

Rationale: When administering an immunization, it is essential to have epinephrine available in case of an allergic reaction such as anaphylaxis. Epinephrine is the medication of choice for treating severe allergic reactions due to its ability to reverse the symptoms rapidly. Diphenhydramine and hydroxyzine are antihistamines that can help manage mild allergic reactions but are not the primary medications for severe reactions like anaphylaxis. Physostigmine is not indicated for managing allergic reactions and is used for specific conditions such as anticholinergic toxicity.

3. A patient is starting on medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse include in the patient teaching?

• A. Take the medication with food to prevent nausea.
• B. Take the medication at the same time each day to maintain consistent hormone levels.
• C. Avoid prolonged sun exposure while taking this medication.
• D. Discontinue the medication if side effects occur.

Correct answer: B

Rationale: The correct answer is B. Patients starting on medroxyprogesterone acetate (Provera) for endometriosis should be instructed to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Choice A is incorrect because medroxyprogesterone acetate can be taken with or without food. Choice C is unrelated to the medication and not a specific concern with its use. Choice D is incorrect as patients should not discontinue the medication without consulting their healthcare provider, even if side effects occur.

4. What specific instructions should the nurse provide for proper administration of alendronate (Fosamax) in a patient with osteoporosis?

• A. Take the medication with milk to enhance calcium absorption.
• B. Take the medication with a full glass of water and remain upright for at least 30 minutes.
• C. Take the medication at bedtime to ensure absorption during sleep.
• D. Take the medication with food to prevent gastrointestinal upset.

Correct answer: B

Rationale: The correct answer is to take alendronate with a full glass of water and remain upright for at least 30 minutes. This is essential to prevent esophageal irritation and ensure proper drug absorption. Choice A is incorrect as alendronate should not be taken with milk due to potential interactions. Choice C is incorrect as there is no need to take the medication at bedtime specifically. Choice D is incorrect as taking alendronate with food can decrease its absorption.

5. A student nurse was asked which of the following best describes dementia. Which of the following best describes the condition?

• A. Memory loss as a natural consequence of aging
• B. Difficulty coping with physical and psychological changes
• C. Severe cognitive impairment that occurs rapidly
• D. Loss of cognitive abilities, impairing the ability to perform activities of daily living

Correct answer: D

Rationale: The correct answer is D. Dementia is characterized by a loss of cognitive abilities that impairs the individual's capacity to perform activities of daily living. Choice A is incorrect because dementia is not simply memory loss related to aging but involves broader cognitive deficits. Choice B is incorrect as it does not capture the comprehensive cognitive decline seen in dementia. Choice C is incorrect as dementia typically progresses gradually rather than rapidly, and it is not solely about severe cognitive impairment but also impacts daily functioning.
