Before helping a resident into a shower the nursing assistant should

Correct Answer: A

Rationale: The correct answer is A: Test the water temperature. This step ensures the resident's safety by preventing burns from hot water. Testing the water temperature is crucial before assisting the resident into the shower to avoid any potential harm. Soaking the resident's fingertips (B), massaging the resident's head (C), and exfoliating the resident's skin with a brush (D) are not necessary steps and do not address the primary concern of ensuring the water temperature is safe for the resident.

Correct Answer: D

Rationale: The correct answer is D: To treat constipation. A rectal suppository contains medication that helps soften stool and stimulate bowel movements, making it an effective treatment for constipation. It is directly inserted into the rectum to deliver the medication. Choices A, B, and C are incorrect because rectal suppositories are not typically used for reducing fecal incontinence, eliminating bouts of diarrhea, or inducing bowel movements.

Correct Answer: D

Rationale: The correct answer is D: Trichomoniasis. Trichomoniasis is caused by a protozoan parasite called Trichomonas vaginalis. This infection is transmitted through sexual contact. The other choices (A, B, C) are caused by viruses (HPV, herpes) or bacteria (syphilis), not protozoa. Trichomoniasis is characterized by symptoms like vaginal discharge, itching, and discomfort during urination. Treatment typically involves antibiotics. In summary, Trichomoniasis is the only option caused by a protozoa, making it the correct answer.

Correct Answer: D

Rationale: The correct answer is D: Systole. During systole, the ventricles contract to pump blood out of the heart. This phase is crucial for maintaining blood circulation and providing oxygen to the body. Flatlining (A) refers to a state of no cardiac activity, which is not related to ventricular contraction. Diastole (B) is the phase when the heart relaxes and fills with blood, opposite to ventricular contraction. Homeostasis (C) is the body's ability to maintain internal stability and is not specific to heart function. In summary, systole is the correct choice as it specifically describes the phase of heart function where the ventricles contract to pump blood, while the other options do not accurately describe this process.

Correct Answer: C

Rationale: The correct answer is C because as individuals age, there is a natural decrease in the ability of the lungs to efficiently exchange oxygen and carbon dioxide, leading to a decrease in oxygen levels in the blood. This is due to factors such as decreased lung elasticity, reduced respiratory muscle strength, and changes in lung structure. Explanation for other choices: A: Air sacs do not increase in the lungs with age, rather they may lose elasticity. B: Chest muscles tend to weaken with age, not strengthen. D: Lung capacity typically decreases with age due to changes in lung function and structure, not increases.
