HESI 799 RN Exit Exam Capstone

Correct Answer: D

Rationale: The first priority in an acute asthma exacerbation is to administer oxygen to improve the client's oxygen saturation. In this scenario, the client has a low oxygen saturation level of 86%, indicating hypoxemia, which can be life-threatening. Administering oxygen therapy will help improve oxygenation and support vital organ function. Once the oxygen levels are stabilized, further interventions such as bronchodilators can be implemented. Placing the client in a high-Fowler's position may also be beneficial, but ensuring adequate oxygenation takes precedence in this critical situation. Obtaining a peak flow reading is important for asthma management but is not the first intervention needed in a client with severe hypoxemia.

Correct Answer: B

Rationale: The correct answer is B: White blood cell count and sputum culture. Monitoring white blood cell count and sputum cultures is essential to assess the effectiveness of the antibiotic in treating the respiratory tract infection. Changes in white blood cell count can indicate the body's response to infection, while sputum cultures help determine if the antibiotic is targeting the specific pathogens causing the infection. Choices A, C, and D are incorrect because platelet count, red blood cell count, hemoglobin A1c, glucose tolerance test, arterial blood gases, and serum electrolytes are not directly related to evaluating the effectiveness of an antibiotic in treating a respiratory tract infection.

Correct Answer: C

Rationale: The most important instruction for the nurse to provide to a client scheduled for a colonoscopy and prescribed a bowel preparation is to take the entire bowel preparation as directed. Completing the entire bowel preparation as prescribed is crucial to ensure the colon is properly cleansed for the colonoscopy. Incomplete bowel prep can interfere with the visualization of the colon, leading to inaccurate results. Choices A, B, and D are important but not as crucial as ensuring the complete intake of the bowel preparation for an effective procedure.

Correct Answer: D

Rationale: Prasugrel is a platelet inhibitor, which increases the risk of bleeding. Monitoring for bleeding, particularly at the catheterization site and in other areas, is the most important assessment following administration of the drug. Checking platelet count and observing urine color are relevant but not as immediate. Reviewing liver function tests is not directly related to the adverse effects of prasugrel.

Correct Answer: B

Rationale: The correct answer is B. A bagel with jelly and skim milk is a calcium-rich and low-fat option that aligns with the dietary recommendations for managing osteoporosis. Osteoporosis is a condition characterized by weak and brittle bones, so it is essential to consume an adequate amount of calcium while avoiding excess fat intake. Choices A, C, and D are not ideal for osteoporosis management as they either lack sufficient calcium, contain high fat content, or both.
