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 with a new diagnosis of amyotrophic lateral sclerosis (ALS) is overwhelmed by his diagnosis and the known complications of the disease. How can the patient best make known his wishes for care as his disease progresses?
- A. Prepare an advance directive.
- B. Designate a most responsible physician (MRP) early in the course of the disease.
- C. Collaborate with representatives from the Amyotrophic Lateral Sclerosis Association.
- D. Ensure that witnesses are present when he provides instruction.
Correct Answer: A
Rationale: The correct answer is A: Prepare an advance directive. This allows the patient to document their healthcare preferences in advance, ensuring their wishes are known and honored as the disease progresses. It provides clear instructions for healthcare providers and family members, reducing potential conflicts and ensuring the patient's autonomy is respected.
Choice B is incorrect as designating an MRP focuses on medical decision-making but may not capture the full range of the patient's care preferences. Choice C involves collaboration with an organization, which may not fully represent the patient's individual wishes. Choice D is incorrect as witnesses are not always necessary for providing instructions, and the presence of witnesses does not guarantee that the patient's wishes will be followed accurately.
The nurse in a pediatric ICU is caring for a child who is dying of sickle cell anemia. The childs mother has been unable to eat or sleep and can talk only about her impending loss and the guilt she feels about the childs pain and suffering. What intervention has the highest priority?
- A. Allowing the patient to express her feelings without judging her
- B. Helping the patient to understand the phases of the grieving process
- C. Reassuring the patient that the childs death is not her fault
- D. Arranging for genetic counseling to inform the patient of her chances of having another child with the disease
Correct Answer: A
Rationale: The correct answer is A: Allowing the patient to express her feelings without judging her. This intervention has the highest priority as it focuses on providing emotional support and creating a safe space for the mother to express her emotions without feeling judged. In this situation, the mother is experiencing intense guilt and grief, and allowing her to talk about her feelings can help her process her emotions and cope with the impending loss. By listening actively and without judgment, the nurse can demonstrate empathy and compassion, which are crucial in supporting the mother through this difficult time.
Summary:
B: Helping the patient to understand the phases of the grieving process may be helpful, but it is not the highest priority at this moment.
C: Reassuring the patient that the child's death is not her fault is important, but the priority is to address the mother's emotional needs first.
D: Arranging for genetic counseling is not the highest priority at this time as the immediate focus should be on providing emotional support to the mother
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 clinic nurse is providing preprocedure education for a man who will undergo a vasectomy. Which of the following measures will enhance healing and comfort? Select all that apply.
- A. Abstaining from sexual intercourse for at least 14 days postprocedure
- B. Wearing a scrotal support garment
- C. Using sitz baths
- D. Applying a heating pad intermittently E) Staying on bed rest for 48 to 72 hours postprocedure
Correct Answer: A
Rationale: The correct answer is A: Abstaining from sexual intercourse for at least 14 days postprocedure. This is important to allow the surgical site to heal properly and reduce the risk of complications. Choice B, wearing a scrotal support garment, can provide comfort but does not directly enhance healing. Choice C, using sitz baths, may help with discomfort but may not specifically promote healing. Choice D, applying a heating pad intermittently, could potentially increase the risk of infection. Choice E, staying on bed rest for 48 to 72 hours postprocedure, is unnecessary and could lead to complications such as blood clots.
The nurse is caring for a patient who has been admitted for the treatment of AIDS. In the morning, the patient tells the nurse that he experienced night sweats and recently coughed up some blood. What is the nurses most appropriate action?
- A. Assess the patient for additional signs and symptoms of Kaposis sarcoma.
- B. Review the patients most recent viral load and CD4+ count.
- C. Place the patient on respiratory isolation and inform the physician.
- D. Perform oral suctioning to reduce the patients risk for aspiration.
Correct Answer: C
Rationale: The correct answer is C: Place the patient on respiratory isolation and inform the physician. This is the most appropriate action because the patient is exhibiting symptoms that could be indicative of a potentially infectious respiratory condition, such as tuberculosis or pneumonia. Placing the patient on respiratory isolation helps prevent the spread of infection to others and protects healthcare workers. Informing the physician promptly allows for further evaluation and appropriate treatment.
Choice A is incorrect as Kaposi's sarcoma typically presents with skin lesions rather than respiratory symptoms. Choice B is incorrect as reviewing viral load and CD4+ count would not address the immediate concern of respiratory symptoms. Choice D is incorrect as oral suctioning is not the appropriate intervention for night sweats and coughing up blood.
