The nurse is preparing to administer an enema to a client with severe constipation. Which position is most appropriate for the client?

Correct Answer: C

Rationale: Sims' position with the right leg flexed is the most appropriate position for administering an enema to a client with severe constipation. This position helps in promoting the flow of the enema solution into the rectum and facilitates the evacuation of stool. Supine position with the head elevated 30 degrees (Choice A) is not ideal for administering an enema as it does not facilitate the flow of the solution. Left lateral position with the right leg flexed (Choice B) is not the best choice for administering an enema. Prone position with the head turned to the side (Choice D) is also not suitable for administering an enema as it does not assist in the proper administration and retention of the solution.

Correct Answer: C

Rationale: In a client with chronic kidney disease receiving erythropoietin therapy, elevated blood pressure is the most concerning assessment finding. Erythropoietin can increase red blood cell production, leading to thicker blood, which in turn can elevate blood pressure. Elevated blood pressure in this scenario may indicate worsening hypertension, which requires prompt intervention to prevent complications such as stroke, heart attack, or further kidney damage. Increased fatigue (choice A) is a common symptom in CKD patients and can be expected with erythropoietin therapy. Headache (choice B) can occur but is less concerning than elevated blood pressure in this context. Low urine output (choice D) is a significant finding in CKD, but in a client receiving erythropoietin, elevated blood pressure takes precedence due to its potential for immediate adverse effects.

Correct Answer: C

Rationale: The correct answer is C. The presence of a new murmur in a client with heart failure receiving digoxin and furosemide is concerning as it may indicate valvular problems or other complications that require immediate intervention. A heart rate of 60 beats per minute and an apical pulse of 58 beats per minute are within normal limits for a client with heart failure on these medications. A blood pressure of 100/60 mmHg, while slightly low, may be expected due to the diuretic effect of furosemide and may not require immediate intervention unless the client is symptomatic.

Correct Answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

Correct Answer: A

Rationale: After an open reduction of the tibia, bleeding on the cast can be a concern. Outlining the area with ink and monitoring it every 15 minutes is the appropriate action to assess if the bleeding is worsening, indicating the need for further intervention. This action allows for close observation without disturbing the cast. Choice B is incorrect because while notifying the healthcare provider is important, immediate action is not always necessary if the bleeding is not severe. Choice C is incorrect because applying a new cast is not the standard intervention for bleeding on a cast. Choice D is incorrect because elevating the limb may not address the underlying cause of bleeding and may not be the most appropriate action at this time.

Correct Answer: C

Rationale: Assessing the client's oxygen saturation is the first priority in managing a client with COPD receiving supplemental oxygen to ensure adequate oxygenation. Monitoring oxygen saturation levels helps in determining the effectiveness of the oxygen therapy and if adjustments are needed. Elevating the head of the bed can help with breathing but is not the first priority. Administering oxygen therapy as prescribed is important, but assessing the current oxygen saturation comes before administering more oxygen. Obtaining an arterial blood gas (ABG) sample may provide valuable information, but it is not the initial intervention needed in this situation.

Correct Answer: D

Rationale: The best client for the charge nurse to assign to a practical nurse (PN) is an older client post-stroke who is aphasic with right-sided hemiplegia. This client is stable and suitable for care by a PN under supervision. Choices A, B, and C present clients with more complex and acute conditions that would require a higher level of nursing expertise and intervention.

Correct Answer: C

Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.

Correct Answer: C

Rationale: A serum ammonia level of 80 mcg/dl is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. Elevated ammonia levels are associated with impaired liver function and can lead to mental status changes. Serum bilirubin (Choice A) is elevated in cirrhosis but not as concerning for acute intervention as high ammonia levels. Serum albumin (Choice B) and serum sodium (Choice D) levels are important in cirrhotic patients but are not as directly associated with hepatic encephalopathy as ammonia levels.
