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 should teach which of the following clients requiring crutches about how to use a three-point gait?

• A. A client who is able to bear full weight on both lower extremities.
• B. A client who has bilateral leg braces due to paralysis of the lower extremities.
• C. A client who has a right femur fracture with no weight bearing on the affected leg.
• D. A client who has bilateral knee replacements with partial weight bearing on both legs.

Correct answer: C

Rationale: The correct answer is C because a three-point gait is used when the client can bear full weight on one foot and uses crutches and the uninvolved leg to ambulate. Choices A, B, and D are incorrect because they do not meet the criteria for using a three-point gait. Choice A states that the client can bear full weight on both lower extremities, which does not require a three-point gait. Choice B mentions bilateral leg braces due to paralysis, which would not involve using a three-point gait. Choice D describes a client with bilateral knee replacements with partial weight bearing, which also does not align with the use of a three-point gait.

3. A healthcare provider is assessing a newborn who is 48 hours old and is experiencing opioid withdrawals. Which of the following findings should the healthcare provider expect?

• A. Hypotonia
• B. Moderate tremors of the extremities
• C. Axillary temperature 36.1°C (96.9°F)
• D. Excessive crying

Correct answer: B

Rationale: The correct answer is B: Moderate tremors of the extremities. In newborns experiencing opioid withdrawals, moderate tremors of the extremities are a common sign. Other signs of opioid withdrawal in newborns may include irritability, feeding difficulties, and gastrointestinal disturbances. Choice A, hypotonia, is not typically associated with opioid withdrawal in newborns. Choice C, an axillary temperature of 36.1°C (96.9°F), falls within the normal range for newborns and is not specifically indicative of opioid withdrawal. Choice D, excessive crying, is not a typical sign of opioid withdrawal in newborns.

4. A nurse is using Naegele’s rule to calculate the expected delivery date for a client whose last menstrual period was in October. What is the expected date?

• A. 711
• B. 1011
• C. 411
• D. 1211

Correct answer: A

Rationale: Using Naegele’s rule, to calculate the expected delivery date, you add one year, subtract three months, and add seven days to the first day of the last menstrual period. If the last menstrual period was in October, adding one year gives October of the following year. Subtracting three months gives July, and adding seven days gives the expected delivery date of July 11th. Therefore, the correct answer is 711. Choice B (1011) is incorrect as it doesn't follow Naegele’s rule calculations. Choices C (411) and D (1211) are also incorrect as they do not align with the correct application of Naegele’s rule.

5. A client with diabetes mellitus is receiving education on foot care. Which of the following instructions should the nurse include?

• A. Apply lotion between the toes.
• B. Cut toenails straight across.
• C. Use a heating pad to warm the feet.
• D. Soak feet in warm water daily.

Correct answer: B

Rationale: The correct answer is B: Cut toenails straight across. This instruction is vital for clients with diabetes as it helps prevent ingrown toenails and infections, reducing the risk of foot ulcers. Applying lotion between the toes (choice A) should be avoided as it can create a moist environment prone to fungal infections. Using a heating pad (choice C) can lead to burns or injuries due to reduced sensation common in diabetes. Soaking feet in warm water daily (choice D) can also increase the risk of skin breakdown and should be avoided.
