1. What is the primary action a healthcare professional should take when a patient with a suspected myocardial infarction (MI) arrives in the emergency department?

• A. Apply a cold compress to the chest
• B. Administer oxygen and obtain an electrocardiogram (ECG)
• C. Encourage the patient to walk to reduce anxiety
• D. Provide a high-carbohydrate meal

Correct answer: B

Rationale: Administering oxygen and obtaining an ECG are crucial initial steps when managing a suspected myocardial infarction (MI). Oxygen helps improve oxygenation to the heart muscle, while an ECG is essential to diagnose an MI promptly. Applying a cold compress, encouraging the patient to walk, or providing a high-carbohydrate meal are not appropriate actions in the initial management of a suspected MI. Applying a cold compress can delay necessary interventions, encouraging the patient to walk may worsen the condition, and providing a high-carbohydrate meal is irrelevant to the immediate needs of a patient with a suspected MI.

2. You are caring for a patient who just gave birth to a 6 lb. 13 oz. baby boy. The infant gave out a lusty cry, had a pink coloration all over his body, had flexed arms and legs, cried when stimulated, and had a pulse rate of 94. What Apgar score would you expect for this baby?

• A. 10
• B. 8
• C. 7
• D. 9

Correct answer: D

Rationale: The Apgar score is a method used to quickly assess the health of newborns. In this scenario, the baby would receive 2 points for color, reflex irritability, and muscle tone, but only 1 point for a pulse rate of 94, resulting in an Apgar score of 9. An Apgar score of 9 indicates that the baby is in good health overall. Choice A (10) is incorrect because a pulse rate of 94 would only score 1 point. Choices B (8) and C (7) are incorrect as the given criteria would lead to a higher score, indicating the baby's good health.

3. A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the nurse reinforce about the action of this adjuvant pain modality?

• A. The discharge of electricity will distract the client's focus from the pain
• B. An infusion of medication in the spinal canal will block pain perception
• C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain

Correct answer: D

Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus to the skin, which can help close the 'gates' in the nervous system to block pain signals from reaching the brain, thus reducing pain perception. Choice A is incorrect because TENS does not distract from pain but rather helps manage it. Choice B is incorrect as it describes a different pain management technique involving medication in the spinal canal. Choice C is incorrect because TENS acts peripherally on nerve conduction rather than dulling pain perception in the cerebral cortex.

4. Which of the following best describes the role of insulin in the body?

• A. Insulin helps break down glucose into energy for the body
• B. Insulin facilitates the movement of glucose into cells
• C. Insulin converts excess glucose into fat for storage
• D. Insulin increases the breakdown of protein into amino acids

Correct answer: B

Rationale: The correct answer is B: Insulin facilitates the movement of glucose into cells. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, where it can be used for energy production. Choice A is incorrect because insulin doesn't break down glucose but rather helps cells take up glucose. Choice C is incorrect as insulin does not directly convert glucose into fat; excess glucose is stored as fat by other processes. Choice D is incorrect as insulin does not increase the breakdown of protein into amino acids; its primary role is in glucose metabolism.

5. While caring for a client with an AV fistula in the left forearm, the PN observed a palpable buzzing sensation over the fistula. What action should the PN take?

• A. Loosen the fistula dressing
• B. Report the presence of a bounding pulse
• C. Document that the fistula is intact
• D. Apply gentle pressure over the site

Correct answer: C

Rationale: A palpable buzzing sensation, known as a thrill, over an AV fistula indicates proper functioning. The correct action for the PN is to document that the fistula is intact. Choice A is incorrect because there is no need to loosen the fistula dressing when the thrill is felt. Choice B is incorrect as a bounding pulse is not related to the observed buzzing sensation. Choice D is incorrect because applying pressure is unnecessary when a thrill is present, indicating proper AV fistula function.
