Correct Answer: A

Rationale: When performing a complete bed bath, it is essential to wash the face first. Washing the face initially helps to maintain the client's privacy and comfort. Additionally, starting with the face prevents re-contamination of already cleaned areas. Washing the feet first (Choice B) is not ideal as it can lead to potential contamination of the upper body parts. Starting with the chest (Choice C) or arms (Choice D) is not recommended due to the risk of water dripping onto the client's face, causing discomfort and compromising privacy.

Correct Answer: A

Rationale: A positive Chvostek's sign is a clinical indication of low calcium levels, known as hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching. The correct laboratory finding associated with a positive Chvostek's sign is decreased calcium. Elevated potassium (Choice B) is not typically associated with Chvostek's sign but can be seen in conditions like renal failure. Increased sodium (Choice C) is not directly related to Chvostek's sign and is more commonly associated with hypernatremia. Low hemoglobin (Choice D) is not the expected laboratory finding in a client with a positive Chvostek's sign; instead, it suggests anemia, which is unrelated to this clinical manifestation.

Correct Answer: A

Rationale: Specific gravity measures the concentration of solutes in the urine, reflecting the kidney's ability to concentrate or dilute urine. Choice B, bacteria in the urine, is incorrect because specific gravity does not measure bacterial presence. Choice C, pH level of the urine, is incorrect as it refers to the acidity or alkalinity of the urine, not its specific gravity. Choice D, glucose in the urine, is incorrect as specific gravity does not directly measure glucose levels in urine.

Correct Answer: B

Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) · Time (min) · Drop factor (gtt/mL). In this case, 1000 mL · 240 min · 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.

Correct Answer: A

Rationale: The correct action to ensure the medication reaches the inner ear is to press gently on the tragus of the client's ear. The tragus is the small pointed eminence of the external ear, and pressing on it helps direct the medication deeper into the ear canal. Pulling the ear lobe up and back (Choice B) is the correct technique for administering eardrops to a child, not an adult. Inserting the medication deeply into the ear canal (Choice C) can cause injury or discomfort as the eardrops are designed to flow into the ear canal naturally. Massaging the ear gently after administering the medication (Choice D) is unnecessary and may not help the medication reach the inner ear effectively.
