HESI 799 RN Exit Exam Capstone
1. A client with a history of adrenal insufficiency is admitted with acute adrenal crisis. The client complains of nausea and joint pain, vital signs show a temperature of 102°F, heart rate of 138, and blood pressure of 80/60. Which intervention should the nurse implement first?
- A. Obtain an analgesic prescription.
- B. Infuse an intravenous fluid bolus.
- C. Administer PRN oral antipyretic.
- D. Cover the client with a cooling blanket.
Correct answer: B
Rationale: In acute adrenal crisis, the priority intervention is to infuse an intravenous fluid bolus to address the hypotension (blood pressure of 80/60) and help stabilize the client's condition. Adequate fluid volume is crucial in managing adrenal insufficiency crisis. Options A, C, and D do not directly address the hypotension and fluid volume depletion that are critical in this situation. Analgesics, antipyretics, and cooling blankets may be considered later, but the immediate focus should be on fluid resuscitation.
2. A client with early breast cancer receives the results of a breast biopsy and asks the nurse to explain the meaning of staging and the type of receptors found on the cancer cells. Which explanation should the nurse provide?
- A. Lymph node involvement is not significant.
- B. Small tumors are aggressive and indicate poor prognosis.
- C. The tumor's estrogen receptor guides treatment options.
- D. Stage I indicates metastasis.
Correct answer: C
Rationale: Treatment decisions and prediction of prognosis are related to the tumor's receptor status, such as estrogen and progesterone receptor status which commonly are well-differentiated, have a lower chance of recurrence, and are receptive to hormonal therapy. Tumor staging designates tumor size and spread of breast cancer cells into axillary lymph nodes, which is one of the most important prognostic factors in early-stage breast cancer.
3. What is the primary nursing intervention for a patient experiencing an acute asthma attack?
- A. Administering bronchodilators.
- B. Administering antibiotics.
- C. Administering IV fluids.
- D. Administering corticosteroids.
Correct answer: A
Rationale: The correct answer is administering bronchodilators. During an acute asthma attack, the primary goal is to relieve airway constriction and bronchospasm to improve breathing. Bronchodilators, such as short-acting beta-agonists, are the cornerstone of treatment as they help dilate the airways quickly. Administering antibiotics (choice B) is not indicated unless there is an underlying bacterial infection. Administering IV fluids (choice C) may be necessary in some cases, but it is not the primary intervention for an acute asthma attack. Administering corticosteroids (choice D) is often used as an adjunct therapy to reduce airway inflammation, but it is not the primary intervention during the acute phase of an asthma attack.
4. In meiosis, the chromosome number is reduced from:
- A. 46 to 23
- B. 46 to 33
- C. 28 to 14
- D. 24 to 12
Correct answer: A
Rationale: The correct answer is A: "46 to 23." In meiosis, the chromosome number is reduced by half to form gametes for sexual reproduction. In humans, where the diploid chromosome number is 46, meiosis results in haploid cells with 23 chromosomes. Choices B, C, and D are incorrect because they do not represent the correct reduction in chromosome number during meiosis.
5. A client with chronic obstructive pulmonary disease (COPD) is receiving supplemental oxygen. The client reports feeling short of breath and has a respiratory rate of 28 breaths per minute. What should the nurse do first?
- A. Increase the oxygen flow rate
- B. Notify the healthcare provider
- C. Administer a bronchodilator
- D. Elevate the head of the bed
Correct answer: D
Rationale: Elevating the head of the bed promotes lung expansion and improves oxygenation, making it the priority intervention for a client with shortness of breath. This position helps in maximizing lung expansion and aiding ventilation-perfusion matching in patients with COPD. Increasing the oxygen flow rate may be necessary but should come after optimizing the client's positioning. Notifying the healthcare provider and administering a bronchodilator are not the initial interventions for addressing shortness of breath in a client with COPD.
