Conductive hearing loss, common

Correct Answer: B

Rationale: The correct answer is B: Middle ear problem. Conductive hearing loss typically results from issues in the middle ear that prevent sound from reaching the inner ear effectively. Common causes include ear infections, fluid buildup, or problems with the ear bones. The inner ear (choice A) is responsible for processing sound signals, not conducting them. Choices C and D are likely left blank as they do not relate to conductive hearing loss.

Correct Answer: B

Rationale: The correct answer is B because snoring often occurs when sleeping on the back (supine position), causing the tongue and soft tissues to collapse towards the back of the throat, obstructing the airway. By lessening the time spent in the supine position or using positional therapy devices to prevent sleeping on the back, the likelihood of snoring can be reduced. Option A, sleeping flat, does not address the specific issue of sleeping on the back. Options C and D are incomplete, and their relevance to snoring prevention is unclear.

Correct Answer: A

Rationale: The sagittal suture runs from the front to the back of the skull, dividing it into left and right halves. This is its primary function, aligning with the midline of the skull. Choice A is correct because it accurately describes the anatomical division created by the sagittal suture. Choices B, C, and D are incorrect because they do not accurately represent the function of the sagittal suture.

Correct Answer: B

Rationale: The correct answer is B because the nurse should be positioned in front of the blind patient, allowing the patient to hold onto the nurse's shoulder from behind. This positioning ensures the patient feels secure and can easily follow the nurse's movements. Placing the nurse at the back (choice A) may cause confusion and not provide the necessary support. Choice C and D are left blank as they do not offer appropriate alternatives.

Correct Answer: A

Rationale: The correct answer is A because standing position typically leads to increased pulse rate due to the body's response to the change in posture. When standing up, blood pools in the lower extremities, causing a temporary drop in blood pressure, which triggers the heart to beat faster to maintain adequate blood flow to the brain and other vital organs. This increase in pulse helps to counteract the drop in blood pressure and prevent dizziness or fainting. Summary: - Choice B (Decreased pulse) is incorrect because standing usually causes an increase in pulse rate. - Choices C and D are not applicable since they are blank.
