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 healthcare provider is among the first responders to a mass-casualty incident and does not know what type of personal protective equipment (PPE) is needed. Which of the following actions should the healthcare provider take?

• A. Use basic gloves and a mask.
• B. Choose the highest level of protection equipment available.
• C. Use only respiratory protection.
• D. Ask a colleague for advice.

Correct answer: B

Rationale: In situations where the type of hazard is unknown, the healthcare provider should choose the highest level of protection equipment available. This helps ensure adequate protection against any potential hazards that may be present. Using only basic gloves and a mask (Choice A) may not provide sufficient protection if the hazard is more severe. Opting for respiratory protection only (Choice C) may leave other areas of the body vulnerable to exposure. While asking a colleague for advice (Choice D) is good practice in general, in urgent situations like mass-casualty incidents with unknown hazards, it is crucial to prioritize immediate protection by selecting the highest level of PPE.

4. A nurse is teaching a client about the dietary management of irritable bowel syndrome (IBS). Which of the following instructions should the nurse include?

• A. Decrease fiber intake
• B. Drink peppermint tea
• C. Increase foods that are high in fat
• D. Avoid foods with gluten

Correct answer: B

Rationale: The correct answer is B: 'Drink peppermint tea.' Peppermint tea can help relax the smooth muscles of the gastrointestinal tract, reducing symptoms of IBS, such as bloating and abdominal discomfort. Choices A, C, and D are incorrect. Decreasing fiber intake is not recommended for IBS management as fiber can help regulate bowel movements. Increasing foods high in fat can exacerbate symptoms of IBS, as high-fat foods can be harder to digest. Avoiding foods with gluten is more relevant for individuals with gluten sensitivity or celiac disease, not specifically for IBS management.

5. A community health nurse is teaching a group of clients about first aid for different types of wounds. Which of the following client statements indicates an understanding of the teaching?

• A. I should apply clean dressings over blood-saturated dressings and hold pressure.
• B. I will rinse the wound with hot water to cleanse it.
• C. I can remove the dressing once the bleeding stops.
• D. I should apply antibiotic ointment directly to the wound.

Correct answer: A

Rationale: The correct answer is A because applying clean dressings over blood-saturated dressings and holding pressure helps prevent disruption of wound tissue, aiding in the clotting process and controlling bleeding. Choice B is incorrect as rinsing a wound with hot water can cause further tissue damage. Choice C is incorrect as the dressing should not be removed once applied as it can disrupt the formation of a clot. Choice D is incorrect as antibiotic ointment should not be applied directly to the wound during initial first aid.
