Correct Answer: C

Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway.
Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea.
Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea.
Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.

Correct Answer: C

Rationale:
To reduce the risk of a needlestick injury, it is essential to keep a sharps container nearby where it can be easily accessed. This practice ensures quick and safe disposal of needles after use, minimizing the chances of accidental needlesticks. Recapping needles should be avoided as it increases the risk of injuries. Passing needles between workers should also be avoided to prevent accidental needle pricks during handovers.
Therefore, the best practice to prevent needlestick injuries is to maintain a sharps container nearby for safe and immediate disposal of needles.

Correct Answer: B

Rationale: The correct answer is 'lateral.' The Sims' position is characterized by the patient lying on their side with the upper knee flexed and the upper arm positioned in front of the body. This is similar to the lateral position where the patient is also lying on their side. The prone position (choice
A) is when the patient lies face down, the supine position (choice
C) is when the patient lies face up, and Fowler's position (choice
D) is a seated position with the head of the bed elevated at a 45-90 degree angle.
Therefore, the lateral position is the most similar to the Sims' position as both involve the patient lying on their side.

Correct Answer: C

Rationale: The stapes, along with the malleus and incus, are the three smallest bones in the human body. These bones are located in the inner ear and play a crucial role in hearing. The vomer is a bone in the nasal cavity and is not one of the smallest bones. The distal phalanx of the small toe is relatively larger and not among the smallest bones. The coccyx, also known as the tailbone, is not one of the smallest bones in the body.

Correct Answer: C

Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (
Choice
D), which has three cusps, making
Choice D incorrect. The left ventricle (
Choice
A) and right atrium (
Choice
B) are not synonymous with the mitral valve.
Therefore, the correct answer is C: Bicuspid valve.
