The nurse is teaching a health class about thegastrointestinal tract. The nurse will explain that which portion of the digestive tract absorbs most of the nutrients?
- A. Ileum
- B. Cecum
- C. Stomach
- D. Duodenum
Correct Answer: D
Rationale: The correct answer is D: Duodenum. The duodenum is the first part of the small intestine where most of the digestion and absorption of nutrients occurs. It receives partially digested food from the stomach and mixes it with bile and pancreatic enzymes to break down nutrients. The villi in the duodenum increase the surface area for absorption. The other choices (A: Ileum, B: Cecum, C: Stomach) are incorrect because the ileum and cecum are parts of the small intestine where some absorption occurs but not as much as in the duodenum. The stomach primarily digests food and does not absorb many nutrients.

A patient has lost most of her vision as a result of macular degeneration. When attempting to meet this patients psychosocial needs, what nursing action is most appropriate?
- A. Encourage the patient to focus on her use of her other senses.
- B. Assess and promote the patients coping skills during interactions with the patient.
- C. Emphasize that her lifestyle will be unchanged once she adapts to her vision loss.
- D. Promote the patients hope for recovery.
Correct Answer: B
Rationale: The correct answer is B because assessing and promoting the patient's coping skills is essential in addressing the psychosocial needs of a patient with macular degeneration. By understanding how the patient is coping with the vision loss, the nurse can tailor interventions to support the patient effectively. This approach acknowledges the patient's emotional responses and helps them navigate the challenges associated with the condition.
Choice A is incorrect as solely focusing on other senses may not address the psychological impact of vision loss. Choice C is incorrect as it dismisses the significant lifestyle changes the patient may experience. Choice D is incorrect as promoting hope for recovery may not be realistic in the case of irreversible conditions like macular degeneration.
A patient got a sliver of glass in his eye when a glass container at work fell and shattered. The glass had to be surgically removed and the patient is about to be discharged home. The patient asks the nurse for a topical anesthetic for the pain in his eye. What should the nurse respond?
- A. Overuse of these drops could soften your cornea and damage your eye.
- B. You could lose the peripheral vision in your eye if you used these drops too much.
- C. Im sorry, this medication is considered a controlled substance and patients cannot take it home.
- D. I know these drops will make your eye feel better, but I cant let you take them home.
Correct Answer: A
Rationale: The correct answer is A. Overuse of topical anesthetics can soften the cornea and damage the eye. Topical anesthetics numb the eye, masking pain and potentially leading to overuse. This can prevent the patient from recognizing potential issues like infection or further injury. Additionally, prolonged use can interfere with the cornea's ability to heal properly. Choices B, C, and D are incorrect because they do not address the specific risks associated with using topical anesthetics in the eye. Option B focuses on peripheral vision loss, which is not a direct consequence of using topical anesthetics. Choice C mentions controlled substances, which is not relevant to the situation. Option D acknowledges the patient's request but does not educate the patient on the potential harm of overusing topical anesthetics.
Anti-infective prophylaxis is indicated for a pregnant patient with a history of mitral valve stenosis related to rheumatic heart disease because the patient is at risk of developing
- A. hypertension.
- B. postpartum infection.
- C. bacterial endocarditis.
- D. upper respiratory infections.
Correct Answer: C
Rationale: The correct answer is C: bacterial endocarditis. Mitral valve stenosis increases the risk of bacterial endocarditis due to turbulent blood flow and potential damage to the heart valve. Prophylactic antibiotics are recommended before certain procedures to prevent bacterial endocarditis in patients with underlying cardiac conditions.
Choice A, hypertension, is incorrect as mitral valve stenosis does not directly increase the risk of developing hypertension. Choice B, postpartum infection, is not directly related to the risk associated with mitral valve stenosis. Choice D, upper respiratory infections, is not a specific risk associated with mitral valve stenosis in pregnant patients.
A patient with a hip fracture is having difficulty defecating into a bedpan while lying in bed. Which action by the nurse will assist the patient in having a successful bowel movement?
- A. Preparing to administer a barium enema
- B. Withholding narcotic pain medication
- C. Administering laxatives to the patient
- D. Raising the head of the bed
Correct Answer: D
Rationale: Rationale: Option D is correct because raising the head of the bed promotes a more natural position for defecation, allowing gravity to assist. This position helps align the rectum and anal canal, making it easier for the patient to have a bowel movement. Administering laxatives (Option C) may help, but adjusting the bed position is a non-invasive and more immediate intervention. Withholding pain medication (Option B) could lead to unnecessary discomfort for the patient. Administering a barium enema (Option A) is not indicated for addressing difficulty with defecation.
A patient has been referred to the breast clinic after her most recent mammogram revealed the presence of a lump. The lump is found to be a small, well-defined nodule in the right breast. The oncology nurse should recognize the likelihood of what treatment?
- A. Lumpectomy and radiation
- B. Partial mastectomy and radiation
- C. Partial mastectomy and chemotherapy
- D. Total mastectomy and chemotherapy
Correct Answer: A
Rationale: The correct answer is A: Lumpectomy and radiation. For a small, well-defined nodule in the breast, lumpectomy (removal of the lump) followed by radiation therapy is usually the treatment of choice for early-stage breast cancer. This approach aims to preserve the breast while ensuring effective treatment. Partial mastectomy (B) involves removing a larger portion of the breast tissue and is not typically necessary for a small, well-defined nodule. Chemotherapy (C) is generally used for more advanced stages of breast cancer or when the cancer has spread beyond the breast. Total mastectomy (D) is considered when the cancer is more extensive or in cases where lumpectomy is not feasible.
