Ability to breathe only in an upright position

Correct Answer: B

Rationale: The correct answer is B: Orthopnea. Orthopnea is a condition where a person can breathe comfortably only when in an upright position. This occurs due to the redistribution of blood and fluid in the body, making it easier to breathe when sitting or standing. Apnea (choice A) refers to the temporary cessation of breathing, not related to body position. Choices C and D are incomplete and do not relate to the ability to breathe in an upright position.

Correct Answer: A

Rationale: The correct answer is A because in a Snellen chart, the first number represents the distance at which the test is conducted, which is typically 20 feet. The second number indicates the distance at which a person with normal vision can read the same line that the patient being tested can read. In this case, 20/80 means the patient can read at 20 feet what a person with normal vision can read at 80 feet. Choice B is incorrect as 80 is not the patient's distance but the standard distance for comparison.

Correct Answer: A

Rationale: To ensure accuracy in measuring the client's height and weight, calibrating the weighing scale is crucial. This step ensures the scale is properly adjusted, providing precise measurements. Asking the patient for their previous height and weight (B) is unnecessary as direct measurements are more accurate. Other choices are not applicable.

Correct Answer: A

Rationale: The correct answer is A: Document. After taking a temperature, it is crucial to document the reading for accurate record-keeping and monitoring. Documenting the temperature allows for tracking trends, assessing changes, and providing necessary information for healthcare providers. Clicking a button (Choice B) or leaving the field blank (Choices C and D) do not fulfill the essential task of documenting the temperature, which is critical for proper healthcare management.

Correct Answer: A

Rationale: The correct answer is A: Obstruction. Middle ear problems can lead to hearing issues due to blockages or obstruction in the ear canal or Eustachian tube. This obstruction can prevent sound waves from reaching the inner ear, affecting hearing. Choices B, C, and D do not directly relate to middle ear problems causing hearing issues. Cochlea is a structure in the inner ear responsible for converting sound vibrations into electrical signals, which is not the primary cause of hearing problems in the middle ear. Choices C and D are likely irrelevant or incomplete options, as they do not provide a logical connection to middle ear problems affecting hearing.
