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.

Correct Answer: B

Rationale: Correct. Naloxone is used to reverse opioid overdose, which can cause respiratory depression. Assessing the respiratory rate before administering naloxone is crucial to monitor the patient's breathing. Choices A, C, and D are important assessments in general patient care but are not specifically crucial before administering naloxone for opioid overdose.

Correct Answer: B

Rationale: Thiazide diuretics are known to cause hypokalemia by increasing potassium excretion in the urine. Therefore, the nurse should monitor the client for low potassium levels. Hyperkalemia (Choice A) is not typically associated with thiazide diuretics. Hyponatremia (Choice C) is more commonly linked with thiazide diuretics due to increased sodium excretion. Hypoglycemia (Choice D) is not a usual concern when a client is receiving thiazide diuretics.

Correct Answer: A

Rationale: The correct answer is to check potassium levels before administering furosemide. Furosemide is a diuretic that can cause hypokalemia (low potassium levels) as a side effect. Monitoring potassium levels is crucial to prevent potential complications related to electrolyte imbalance. Assessing blood glucose levels (choice B) is not directly related to furosemide administration. Monitoring respiratory rate (choice C) is important in certain situations, but it is not the priority before administering furosemide. Administering furosemide with food (choice D) is not a requirement as it can be administered regardless of meals.

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.
