Nursing Elites

1. A client admitted with an episode of bleeding esophageal varices is receiving propranolol (Inderal LA). The nurse knows to monitor for?

• A. Hypertension
• B. Hyperkalemia
• C. Bradycardia
• D. Arthralgia

Correct answer: C

Rationale: The correct answer is 'Bradycardia.' Propranolol is a beta-blocking agent used to decrease the heart rate. In the case of bleeding esophageal varices, propranolol is given to reduce the risk of bleeding by keeping the heart rate around 55 beats per minute. Monitoring for bradycardia is essential as the medication's intended effect is to lower the heart rate. Choices A, B, and D are incorrect because propranolol would not typically cause hypertension, hyperkalemia, or arthralgia.

2. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

• A. PaO2 90 mm Hg
• B. Bicarbonate 15 mEq/L
• C. CO2 47 mm Hg
• D. pH 7.34

Correct answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.

3. A client with sleep apnea has been ordered a CPAP machine. Which action could the RN delegate to a nursing assistant?

• A. Reminding the client to apply the CPAP at bedtime
• B. Obtaining every three-hour oxygen saturation levels
• C. Teaching the client how to turn on the CPAP machine
• D. Assessing for fatigue or depression caused by poor sleep

Correct answer: A

Rationale: The correct answer is reminding the client to apply the CPAP at bedtime. This task can be safely delegated to a nursing assistant as it involves a simple and routine reminder. Option B, obtaining oxygen saturation levels, requires a higher level of training and interpretation of results, making it more appropriate for an RN. Option C, teaching the client how to turn on the CPAP machine, involves educating the client and ensuring proper use of medical equipment, which is within the RN's scope of practice. Option D, assessing for fatigue or depression, requires a comprehensive evaluation that involves interpreting symptoms and identifying underlying causes, making it more suitable for an RN to address.

4. Nurses should understand the chain of infection because it refers to:

• A. the linkages involved in disease transmission.
• B. the sequence required for transmission of disease.
• C. the clustering of bacteria in a specific pattern.
• D. increasing virulence patterns among microorganisms.

Correct answer: B

Rationale: The chain of infection refers to the sequence required for the transmission of disease, involving steps like the pathogen's presence, movement from a reservoir, and entry into a susceptible host. Understanding this sequence helps healthcare professionals, including nurses, in implementing effective infection control measures. Choices A, C, and D are incorrect because they do not accurately describe the concept of the chain of infection. Choice A is too broad and does not specifically address the sequential nature of disease transmission. Choice C focuses on bacterial clustering rather than the transmission process. Choice D mentions virulence patterns, which are not the primary focus of the chain of infection concept.

5. A 46-year-old has returned from a heart catheterization and wants to get up to start walking 3 hours after the procedure. The nurse should:

• A. Tell the patient to remain with the leg straight for at least another hour and check the chart for activity orders.
• B. Allow the patient to begin limited ambulation with assistance.
• C. Recommend a physical therapy consultation for ambulation.
• D. Tell the patient to remain with the leg straight for another 6 hours and check the chart for activity orders.

Correct answer: A

Rationale: The correct answer is to tell the patient to remain with the leg straight for at least another hour after a heart catheterization before starting ambulation. This period allows for proper healing and reduces the risk of complications such as bleeding or hematoma formation at the catheter insertion site. Starting ambulation too soon can disrupt the healing process and lead to adverse events. Choice B is incorrect because limited ambulation should not be initiated shortly after the procedure as it may increase the risk of complications. Choice C is incorrect as physical therapy consultation is not typically necessary for initial ambulation post-heart catheterization; this can be managed by nursing staff. Choice D is incorrect as keeping the leg straight for 6 hours is excessive and unnecessary, potentially leading to complications such as deep vein thrombosis due to prolonged immobility.
