test bank foundations of nursing

Correct Answer: A

Rationale: The correct answer is A: Maintaining a closed urinary drainage system. This action prevents infection by reducing exposure to external pathogens. Step 1: A closed system minimizes the risk of contamination. Step 2: It prevents entry of bacteria into the urinary tract. Step 3: Regularly emptying the drainage bag helps maintain a closed system. Step 4: This action promotes patient safety and reduces infection risk. Summary: Choice B (strict clean technique) may reduce infection risk during catheter insertion but does not prevent infections post-insertion. Choice C (replacing drainage bag once per shift) increases infection risk due to frequent disconnection. Choice D (fully inflating catheter balloon) is unrelated to infection prevention.

Correct Answer: A

Rationale: The correct answer is A: Provide emotional support to the patient and her family. This is the priority as the patient has received devastating news and needs immediate support. Emotional support can help the patient cope with the diagnosis, express feelings, and make decisions. B: Implementing distraction techniques may not address the patient's emotional needs in this critical situation. C: Offering to inform the family of the diagnosis is important but not the priority at this moment. D: Teaching about maintaining a positive attitude may not be appropriate as the patient is facing a terminal illness.

Correct Answer: A

Rationale: The correct answer is A: Limit fluid and caffeine intake before bed. This recommendation addresses the issue of nocturia (frequent urination at night) by reducing the amount of urine produced before bedtime, therefore decreasing the need to get up during the night. Caffeine is a diuretic, so limiting its intake can also help reduce the frequency of urination. Choices B, C, and D do not directly address the underlying cause of nocturia and falling. Leaving the bathroom light on (choice B) may help with visibility but does not address the urinary problem. Kegel exercises (choice C) focus on pelvic floor muscles, not bladder muscles. Clearing the path to the bathroom (choice D) can prevent falls but does not address the urinary issue.

Correct Answer: D

Rationale: The correct answer is D because being aware of patients' medication regimens allows nurses to identify and monitor ototoxic medications that can cause hearing loss. By collaborating with other professionals, nurses can adjust medications or recommend alternative treatments to prevent or minimize ototoxicity. This proactive approach directly targets the root cause of potential hearing loss. A: Understanding types of hearing loss is important but does not directly prevent ototoxicity. B: Educating about age-related changes in hearing does not address ototoxicity prevention. C: Educating about noise exposure risks is important for overall hearing health but does not specifically prevent ototoxicity.

Correct Answer: B

Rationale: The correct answer is B: Contraction of bronchial smooth muscle. Histamine release can lead to bronchoconstriction, which narrows the airways and causes difficulty in breathing. This is a common symptom in allergic reactions like asthma. Constriction of small venules (Choice A) is not a typical consequence of histamine release. Dilation of large blood vessels (Choice C) is more associated with histamine's role in increasing vascular permeability. Decreased secretions from gastric and mucosal cells (Choice D) is not directly related to histamine's effects on smooth muscle contraction.
