Nursing Elites

1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. A healthcare professional is preparing to administer 250 mg of an antibiotic IM. Available is 3 g/5 mL. How many mL would the healthcare professional administer per dose?

• A. 0.4 mL
• B. 0.3 mL
• C. 0.5 mL
• D. 0.6 mL

Correct answer: A

Rationale: To calculate the mL to be administered, convert 250 mg to grams (0.25 g). Then, set up a proportion: (0.25 g / 3 g) x 5 mL = 0.4167 mL, which rounds to 0.4 mL. Therefore, the healthcare professional would administer 0.4 mL per dose. Choice B (0.3 mL) is incorrect because it does not reflect the accurate calculation. Choice C (0.5 mL) is incorrect as it does not consider the correct conversion and calculation. Choice D (0.6 mL) is incorrect as it provides a value higher than the accurate calculation.

3. A 65-year-old client is taking methylprednisolone. What pharmacological action should the nurse expect with this therapy?

• A. Suppression of beta2 receptors.
• B. Suppression of airway mucus production.
• C. Fortification of bones.
• D. Suppression of candidiasis.

Correct answer: B

Rationale: The correct answer is B: 'Suppression of airway mucus production.' Methylprednisolone, a corticosteroid, is known to suppress airway mucus production. While corticosteroids can enhance the responsiveness of beta2 receptors, they are not directly involved in the suppression of these receptors (Choice A). Corticosteroids can lead to adverse effects such as bone loss, rather than fortification of bones (Choice C). They can also increase the risk of infections like candidiasis but do not directly suppress it (Choice D). Therefore, the most expected pharmacological action of methylprednisolone therapy is the suppression of airway mucus production.

4. A nurse is caring for a group of clients. Which of the following clients should the nurse assign to an assistive personnel (AP)?

• A. Client who has chronic obstructive pulmonary disease and needs guidance with incentive spirometry
• B. Client who has awoken following a bronchoscopy and requests a drink
• C. Client who had a myocardial infarction 3 days ago and reports chest discomfort
• D. Client who had a cerebrovascular accident 2 days ago and needs help toileting

Correct answer: D

Rationale: The correct answer is D because the client who had a cerebrovascular accident 2 days ago and needs help toileting is stable and the task is appropriate for delegation to an assistive personnel (AP). Choices A, B, and C involve clients with more complex care needs that require the expertise of a nurse. Choice A involves providing guidance with incentive spirometry, which requires specialized knowledge and assessment skills. Choice B involves a client who has just undergone a bronchoscopy, so close monitoring is essential to assess for any complications. Choice C involves a client who had a myocardial infarction 3 days ago and is reporting chest discomfort, which could indicate a potential cardiac issue requiring immediate nursing assessment and intervention.

5. A nurse is preparing to administer a dose of iron supplement. Which of the following should the nurse do?

• A. Give it with milk
• B. Administer it on an empty stomach
• C. Check blood pressure
• D. Monitor for allergic reactions

Correct answer: B

Rationale: The correct answer is B: Administer it on an empty stomach. Iron supplements are best absorbed on an empty stomach to enhance their absorption. It is important to avoid giving them with milk or dairy products as these can inhibit iron absorption. Checking blood pressure and monitoring for allergic reactions are not directly related to the administration of iron supplements and are not the primary considerations in this case.
