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 caring for a client in the second trimester of pregnancy and asks how to treat constipation. Which of the following statements by the nurse is appropriate?

• A. Decrease intake of vitamins and supplements to every other day
• B. Eat 15 g of fiber per day
• C. Consume 48 ounces of water each day
• D. Drink hot water with lemon juice each morning

Correct answer: D

Rationale: The correct answer is D. Drinking hot water with lemon juice in the morning is a natural and safe way to stimulate bowel movements and relieve constipation during pregnancy. Option A is incorrect as vitamins and supplements should not be decreased without consulting a healthcare provider, especially during pregnancy. Option B is inadequate as the recommended daily fiber intake during pregnancy is higher than 15g. Option C, while important for overall health, does not directly address constipation relief in pregnancy.

3. A charge nurse is discussing the use of applying ice to a client’s injured knee with a newly licensed nurse. Which of the following is a benefit of this treatment?

• A. Systemic analgesic effect
• B. Increase in metabolism
• C. Decreased capillary permeability
• D. Vasodilation

Correct answer: C

Rationale: The correct answer is C: Decreased capillary permeability. Ice application helps decrease capillary permeability, which in turn reduces swelling and inflammation at the injury site. This vasoconstriction effect helps to limit the extent of the injury. Choices A, B, and D are incorrect. Applying ice locally does not produce a systemic analgesic effect but rather a localized numbing effect. It does not increase metabolism but rather slows down metabolic processes in the affected area. Additionally, ice application causes vasoconstriction, not vasodilation.

4. A nurse is caring for an older adult who has a non-palpable skin lesion that is less than 0.5 cm in diameter. Which term should the nurse use to document this finding?

• A. Vesicle
• B. Macule
• C. Papule
• D. Nodule

Correct answer: B

Rationale: The correct answer is B: Macule. A macule is a non-palpable skin lesion smaller than 1 cm in diameter. In this case, the skin lesion described is less than 0.5 cm, making it consistent with a macule. Vesicle (choice A) is a small blister filled with clear fluid, papule (choice C) is a solid, raised skin lesion less than 0.5 cm in diameter, and nodule (choice D) is a palpable, solid lesion larger than 0.5 cm in diameter. Therefore, choices A, C, and D describe skin lesions that do not match the characteristics of the lesion presented in the question.

5. A nurse is assessing a client who reports chest pain. Which of the following findings should cause the nurse to suspect a myocardial infarction?

• A. Pain improves with rest
• B. Pain radiates to the left arm.
• C. Pain worsens with deep breathing.
• D. Pain is relieved by antacids.

Correct answer: B

Rationale: The correct answer is B. Radiating pain, especially to the left arm, is a classic sign of myocardial infarction. Pain that radiates to the left arm indicates cardiac involvement, making it a significant finding. Choices A, C, and D are incorrect because chest pain that improves with rest, worsens with deep breathing, or is relieved by antacids is less likely to be associated with a myocardial infarction.
