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 nurse is teaching a group of clients about measures to prevent the development of skin cancer. Which of the following client statements indicates a need for further teaching?

• A. I will avoid going outside between 1000 and 1600.
• B. I will wear a wide-brimmed hat when I go outside.
• C. I will make sure to apply sunscreen with SPF 10 when I’m in the sun.
• D. I will reapply my sunscreen every 2 hours.

Correct answer: C

Rationale: The correct answer is C. An SPF of at least 15 is recommended to effectively protect against harmful UV rays. A sunscreen with an SPF of 10 is insufficient and does not provide adequate protection against skin cancer. Choices A, B, and D demonstrate good understanding of sun protection measures, such as avoiding peak sun hours, wearing protective clothing like a wide-brimmed hat, and reapplying sunscreen every 2 hours, which are all effective strategies to prevent skin cancer.

3. A client has been prescribed enoxaparin. Which of the following instructions should the nurse provide regarding self-administration?

• A. Pinch the skin and inject at a 45-degree angle
• B. Massage the injection site after administering
• C. Administer at a 90-degree angle
• D. Avoid rotating injection sites

Correct answer: A

Rationale: The correct answer is to pinch the skin and inject at a 45-degree angle when administering enoxaparin. This technique helps ensure proper administration of the medication. Massaging the injection site after administering is unnecessary and could increase the risk of bleeding. Administering at a 90-degree angle is not recommended for enoxaparin injections. Rotating injection sites is important to prevent tissue damage and irritation.

4. A client with ulcerative colitis has a new prescription for sulfasalazine. What adverse effect should the client monitor for according to the nurse?

• A. Jaundice
• B. Constipation
• C. Oral candidiasis
• D. Sedation

Correct answer: A

Rationale: The correct answer is A: Jaundice. Sulfasalazine can lead to liver toxicity, making it essential to monitor for jaundice, a sign of liver dysfunction. Choices B, C, and D are incorrect because constipation, oral candidiasis, and sedation are not commonly associated with sulfasalazine use.

5. A charge nurse is providing teaching to a newly licensed nurse on how to clean surfaces contaminated with blood. Which of the following agents should the nurse include in the teaching?

• A. Hydrogen peroxide
• B. Chlorhexidine
• C. Isopropyl alcohol
• D. Chlorine bleach

Correct answer: D

Rationale: Chlorine bleach is the recommended agent for cleaning blood spills due to its effectiveness in killing bloodborne pathogens like HIV and hepatitis B. Hydrogen peroxide, Chlorhexidine, and Isopropyl alcohol are not as effective as chlorine bleach in disinfecting surfaces contaminated with blood and eliminating bloodborne pathogens, making them incorrect choices.
