Before measuring the client's height and weight, you must:

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: 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.

Correct Answer: A

Rationale: The correct answer is A: Disease. An alteration in body function refers to a disruption in the normal physiological processes of the body, which is characteristic of a disease. Diseases can manifest as changes in organ function, biochemical pathways, or cellular processes. Illness, on the other hand, is a subjective feeling of being unwell and does not necessarily imply an underlying physiological dysfunction. Choice C and D are incomplete and do not provide a relevant response to the question.

Correct Answer: A

Rationale: The correct answer is A: Autoclave. An autoclave is the most effective method for sterilizing equipment in a community setting due to its ability to reach high temperatures and pressure to kill all microorganisms. Handwashing (B) is important for reducing the spread of germs but does not achieve sterilization. Boiling water (C) can kill some bacteria and viruses but may not be sufficient for sterilization. Choice D is not provided, so it is not a valid option. Autoclaving ensures complete sterilization, making it the best choice for community sterilization needs.

Correct Answer: A

Rationale: Fluoxetine (Prozac): A selective serotonin reuptake inhibitor (SSRI) which reduces the uptake of serotonin in the brain and is taken to treat depression. Loss of sexual desire is a well-documented side effect.
