foundation of nursing questions and answers

Correct Answer: B

Rationale: The correct answer is B, emptying the pouch if it is more than one-third to one-half full. This action is appropriate to prevent leakage and skin irritation. When the pouch becomes too full, it can put pressure on the seal, leading to potential leaks. Emptying the pouch at one-third to one-half fullness helps maintain a secure seal and prevents skin breakdown. Choice A is incorrect because changing the skin barrier portion of the ostomy pouch daily is unnecessary and can lead to skin irritation and breakdown. Choice C is incorrect because cleansing the skin around the stoma with soap and water excessively can strip the skin of its natural oils and cause irritation. Choice D is incorrect because leaving a 1/2-inch space around the stoma when measuring for the barrier device may result in an improper fit, leading to leakage and skin issues.

Correct Answer: A

Rationale: The correct answer is A: Blowing up balloons. Blowing up balloons involves the activation of the facial muscles, which helps prevent muscle atrophy in patients with Bell's palsy. This exercise promotes muscle strength and prevents weakness. Deliberately frowning (B), smiling repeatedly (C), and whistling (D) do not specifically target the facial muscles involved in Bell's palsy and may not be as effective in preventing muscle atrophy.

Correct Answer: A

Rationale: The correct answer is A because thorough handwashing is essential in preventing the spread of genital herpes. This helps reduce the risk of transmission to other parts of the body or to other individuals. Sunbathing (B) does not eradicate the virus and can actually worsen symptoms. Massaging lesions with ointment (C) can aggravate the sores and lead to further infection. Self-infection (D) can occur from touching lesions during a breakout due to the highly contagious nature of the virus. Therefore, teaching the patient about thorough handwashing is crucial in managing and preventing the spread of genital herpes.

Correct Answer: A

Rationale: Rationale: The correct answer is A because rods are responsible for vision in low light conditions. By ensuring adequate lighting in the patient's room, the nurse can optimize the patient's visual acuity. This will help the patient navigate their environment more safely. Summary: - B is incorrect because dim lighting would further limit the patient's already compromised vision. - C is incorrect as the patient's ability to perceive color may not be affected by rod dysfunction. - D is incorrect as the patient may struggle to see fine details due to rod impairment.

Correct Answer: D

Rationale: The correct answer is D: Different molecular structure in the cells. Malignant cells have alterations in their molecular structure, leading to uncontrolled growth and invasion of surrounding tissues, while benign cells retain their normal molecular structure and do not invade nearby tissues. This distinction is crucial in understanding why malignant cells are cancerous and pose a greater risk compared to benign cells. Other choices are incorrect because: A: Slow rate of mitosis of cancer cells - Malignant cells actually have a rapid rate of mitosis, contributing to their uncontrolled growth. B: Different proteins in the cell membrane - While there may be differences in proteins, the molecular structure is a more fundamental difference between malignant and benign cells. C: Differing size of the cells - Cell size alone is not a definitive characteristic that distinguishes between malignant and benign cells; molecular structure plays a more significant role.
