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.

Correct Answer: B

Rationale: The correct answer is B: 'During the inhalation.' Administering the medication while inhaling ensures proper delivery to the lungs. Inhaling the medication allows it to reach the lungs effectively for optimal therapeutic benefit. Choices A, C, and D are incorrect because administering the medication after exhalation or at the end of inhalations may result in improper drug delivery and reduced therapeutic effects.

Correct Answer: C

Rationale: The correct answer is C: Friction. The amount of friction is crucial in effective hand hygiene to remove microorganisms. Rubbing hands together with friction helps to dislodge and remove dirt, oils, and microorganisms. While temperature and soap are important factors in hand hygiene, the mechanical action of friction plays a more significant role in physically removing contaminants. Time is also important in hand hygiene practice, but without adequate friction, the effectiveness of the process is compromised.

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: C

Rationale: The nurse most likely observed plantar warts, which appear on the sole of the foot and are caused by the papillomavirus. Corns (Choice A) and calluses (Choice B) are areas of thickened skin caused by pressure or friction and are not typically associated with viruses. Athlete's foot (Choice D) is a fungal infection that usually affects the skin between the toes and is not caused by a virus like plantar warts.
