A perinatal client is admitted to the obstetric unit during an exacerbation of a heart condition. When planning for the nutritional requirements which dietary intervention should the nurse consult the dietitian about?
- A. A low-calorie diet to prevent weight gain
- B. A diet low in fluids and fiber to decrease blood volume
- C. A diet adequate in fluids and fiber to decrease constipation
- D. Unlimited sodium intake to increase circulating blood volume
Correct Answer: C
Rationale: Constipation can cause the client to use Valsalva's maneuver. This maneuver can cause blood to rush to the heart and overload the cardiac system. A low-calorie diet is not recommended during pregnancy. Diets low in fluid and fiber can cause a decrease in blood volume that can deprive the fetus of nutrients; it can also lead to constipation. Therefore, adequate fluid intake and high-fiber foods are important. Sodium should be restricted to some degree as prescribed by the primary health care provider because this will cause an overload to the circulating blood volume and contribute to cardiac complications.

The nurse determines that a tuberculin skin test is positive. Which diagnostic test should the nurse anticipate will be prescribed to confirm a diagnosis tuberculosis (TB)?
- A. Chest x-ray
- B. Sputum culture
- C. Complete blood cell count
- D. Computed tomography scan of the chest
Correct Answer: B
Rationale: Although the findings of the chest x-ray examination are important, it is not possible to make a diagnosis of TB solely on the basis of this examination because other diseases can mimic the appearance of TB. The demonstration of tubercle bacilli bacteriologically is essential for establishing a diagnosis. The microscopic examination of sputum for acid-fast bacilli is usually the first bacteriological evidence of the presence of tubercle bacilli. Options 3 and 4 will not diagnose TB.
The nurse is preparing a plan of care for a child diagnosed with leukemia who is beginning chemotherapy. Which intervention should the nurse include?
- A. Monitor rectal temperatures every 4 hours.
- B. Monitor the mouth and anus each shift for signs of breakdown.
- C. Encourage the child to consume fresh fruits and vegetables to maintain nutritional status.
- D. Provide meticulous mouth care several times daily using an alcohol-based mouthwash and a toothbrush.
Correct Answer: B
Rationale: When the child is receiving chemotherapy, the nurse should assess the mouth and anus each shift for ulcers, erythema, or breakdown. The nurse should avoid taking rectal temperatures. Oral temperatures are also avoided if mouth ulcers are present. Axillary or temporal temperatures should be taken to prevent alterations in skin integrity. Bland, nonirritating foods and liquids should be provided to the child. Fresh fruits and vegetables need to be avoided because they can harbor organisms. Chemotherapy can cause neutropenia, and the child should be maintained on a low-bacteria diet if the white blood cell count is low. Meticulous mouth care should be performed, but the nurse should avoid alcohol-based mouthwashes and should use a soft-bristled toothbrush.
The home care nurse is preparing a plan of care for a client diagnosed with Ménière's syndrome. Which nursing intervention should the nurse include to assist the client with controlling vertigo?
- A. Instruct the client to cut down on cigarette smoking.
- B. Encourage the client to increase the daily fluid intake.
- C. Encourage the client to avoid sudden head movements.
- D. Instruct the client to increase the amount of sodium in the diet.
Correct Answer: C
Rationale: Ménière's syndrome refers to dilation of the endolymphatic system by overproduction or decreased resorption of endolymphatic fluid. The nurse instructs the client to make slow head movements to prevent worsening of the vertigo. Clients are advised to stop smoking because of its vasoconstrictive effects. Dietary changes such as salt and fluid restrictions that reduce the amount of endolymphatic fluid are sometimes prescribed.
The nurse is preparing discharge plans for a hospitalized client who attempted suicide. Which intervention should the nurse include in the plan as an immediate resource?
- A. Scheduling weekly follow-up appointments
- B. Establishing contracts with available crisis resources
- C. Encouraging family and friends to be with the client at all times
- D. Providing phone numbers for the hospital and primary health care provider
Correct Answer: B
Rationale: Crisis times may occur between appointments. Contracts facilitate a client's feeling of responsibility for keeping a promise, which gives him or her control. Providing phone numbers will not ensure available and immediate crisis intervention. Family and friends cannot always be present.
The nurse is caring for a postpartum client with thromboembolytic disease. Which intervention is most important to include when planning care to prevent the complication of pulmonary embolism?
- A. Enforce bed rest.
- B. Monitor the vital signs frequently.
- C. Assess the breath sounds frequently.
- D. Administer prescribed anticoagulant therapy.
Correct Answer: D
Rationale: The purposes of anticoagulant therapy for the treatment of thromboembolytic disease are to prevent the formation of a clot and to prevent a clot from moving to another area, thus preventing pulmonary embolism. Although the remaining options may be implemented for a client with thromboembolytic disease, the correct option will specifically assist in the prevention of pulmonary embolism.
