Nursing Elites

1. A client who is receiving heparin therapy has an activated partial thromboplastin time (aPTT) of 90 seconds. What action should the nurse take?

• A. Increase the heparin infusion rate.
• B. Notify the healthcare provider.
• C. Apply pressure to the injection site.
• D. Administer protamine sulfate.

Correct answer: B

Rationale: An activated partial thromboplastin time (aPTT) of 90 seconds is elevated, indicating a risk of bleeding. The appropriate action for the nurse is to notify the healthcare provider. Increasing the heparin infusion rate can further elevate the aPTT, leading to an increased risk of bleeding. Applying pressure to the injection site is not relevant in this situation. Administering protamine sulfate is used to reverse the effects of heparin in cases of overdose or bleeding, but it is not the initial action for an elevated aPTT.

2. A client with a new diagnosis of diabetes mellitus is learning to self-administer insulin. Which instruction should the nurse include?

• A. Store the insulin in the freezer.
• B. Administer the insulin at the same site each time.
• C. Rotate injection sites within the same region.
• D. Shake the vial vigorously before drawing up the insulin.

Correct answer: C

Rationale: The correct instruction for a client learning to self-administer insulin is to rotate injection sites within the same region. This practice helps prevent lipodystrophy, which is a condition characterized by fat tissue changes due to repeated injections in the same spot, and also ensures consistent absorption of insulin throughout the body. Storing insulin in the freezer is incorrect as it can lead to denaturation of the insulin. Administering the insulin at the same site each time can cause lipodystrophy and inconsistent absorption. Shaking the vial vigorously before drawing up the insulin is also incorrect as it can lead to insulin degradation.

3. A 70-year-old man presents with sudden onset of severe abdominal pain. He has a history of atrial fibrillation. Physical examination reveals a soft abdomen with minimal tenderness. What is the most likely diagnosis?

• A. Acute pancreatitis
• B. Mesenteric ischemia
• C. Peptic ulcer disease
• D. Diverticulitis

Correct answer: B

Rationale: The sudden onset of severe abdominal pain in a patient with atrial fibrillation, along with a soft abdomen and minimal tenderness on examination, suggest mesenteric ischemia due to embolic occlusion of the mesenteric arteries. This condition is characterized by a sudden and severe decrease in blood flow to the intestines, leading to abdominal pain and tenderness. Acute pancreatitis typically presents with epigastric pain that may radiate to the back, accompanied by elevated serum amylase and lipase levels. Peptic ulcer disease and diverticulitis usually do not manifest with the sudden onset of severe abdominal pain as described in the case.

4. What skin care instructions should the nurse give to a patient receiving external beam radiation therapy for cancer treatment?

• A. Use a heating pad to relieve any pain in the treated area.
• B. Apply alcohol-based lotions to the treated area daily.
• C. Avoid exposing the treated area to sunlight.
• D. Wash the treated area with hot water and strong soap.

Correct answer: C

Rationale: Patients undergoing external beam radiation therapy should be advised to avoid exposing the treated area to sunlight to prevent further skin damage. Heat sources like heating pads should be avoided to prevent burns and irritation to the skin. Alcohol-based lotions can be irritating to the skin and are not recommended. Washing the treated area with lukewarm water and mild soap is preferable to maintain skin integrity and prevent irritation. Therefore, the correct instruction for the patient is to avoid exposing the treated area to sunlight.

5. The healthcare provider is caring for a client with a chest tube. Which assessment finding requires immediate intervention?

• A. Intermittent bubbling in the water seal chamber.
• B. Drainage of 75 ml in the first hour post-insertion.
• C. Crepitus around the insertion site.
• D. Fluctuation of the water level in the water seal chamber with respiration.

Correct answer: C

Rationale: Crepitus (subcutaneous emphysema) around the insertion site can indicate air leakage, requiring immediate intervention to prevent complications such as pneumothorax. This assessment finding suggests that there may be a break in the chest tube system, leading to air entering the pleural space. Prompt intervention is crucial to prevent respiratory compromise and further complications.
