Nursing Elites

1. A nurse is assessing the chest tube drainage system of a postoperative client who has undergone a right upper lobectomy. The closed drainage system contains 300 mL of bloody drainage, and the nurse notes intermittent bubbling in the water seal chamber. One hour after the initial assessment, the nurse notes that the bubbling in the water seal chamber is now constant, and the client appears dyspneic. On the basis of these findings, the nurse should first assess:

• A. The client’s vital signs
• B. The amount of drainage
• C. The client’s lung sounds
• D. The chest tube connections

Correct answer: D

Rationale: The client’s dyspnea is most likely related to an air leak caused by a loose connection in the chest tube system. Checking the chest tube connections should be the initial action because correcting an air leak can quickly resolve the client's symptoms. If a leak is found and corrected, the dyspnea should improve. Assessing the client’s vital signs (Option A) is important, but addressing the potential cause of dyspnea takes precedence. Monitoring the amount of drainage (Option B) is necessary for assessing the client's overall condition, but in this case, the dyspnea is likely due to an air leak. Checking the client’s lung sounds (Option C) is essential for respiratory assessment, but addressing the air leak should be the immediate priority to ensure adequate lung expansion and oxygenation.

2. The nurse is preparing to administer trimethoprim-sulfamethoxazole (TMP-SMX) to a patient who is being treated for a urinary tract infection. The nurse learns that the patient has type 2 diabetes mellitus and takes a sulfonylurea oral antidiabetic drug. The nurse will monitor this patient closely for which effect?

• A. Headaches
• B. Hypertension
• C. Hypoglycemia
• D. Superinfection

Correct answer: C

Rationale: When a patient takes oral antidiabetic agents (sulfonylurea) along with sulfonamides like trimethoprim-sulfamethoxazole, it can lead to an increased hypoglycemic effect. Therefore, the nurse should monitor the patient closely for hypoglycemia. Headaches, hypertension, and superinfection are not typically associated with the interaction between sulfonamides and sulfonylureas. Examples of antidiabetic sulfonylurea medications include glipizide, glimepiride, glyburide, tolazamide, and tolbutamide.

3. A client who underwent lobectomy 24 hours ago has not had any chest tube drainage for the past hour. What should the nurse do first?

• A. Contacts the physician
• B. Checks for kinks in the drainage system
• C. Checks the client’s blood pressure and heart rate
• D. Connects a new drainage system to the client’s chest tube

Correct answer: B

Rationale: When a chest tube is not draining, the nurse's initial action should be to check for kinks or clots in the chest drainage system. This step helps to ensure the patency of the system and allows for proper drainage. Checking the client's blood pressure and heart rate is important but not the priority when addressing a lack of chest tube drainage. Contacting the physician is warranted if signs of respiratory distress or mediastinal shift are observed after ruling out kinks or clots. Connecting a new drainage system is done when the fluid chamber is full, following a specific procedure to maintain a closed system and prevent complications.

4. The healthcare provider provides dietary instructions about iron-rich food to a client with iron deficiency anemia. Which food selection made by the client indicates a need for additional instructions?

• A. Liver
• B. Kidney beans
• C. Oranges
• D. Leafy green vegetables

Correct answer: C

Rationale: Oranges are not a good source of iron, so selecting oranges indicates a need for additional instructions. Oranges are high in vitamin C, which can enhance iron absorption from other sources, but they are not rich in iron themselves. Liver, kidney beans, and leafy green vegetables are good sources of iron and would be beneficial for a client with iron deficiency anemia. Therefore, the correct answer is C.

5. The patient is taking hydrochlorothiazide (HydroDIURIL) and digoxin (Lanoxin). Which potential electrolyte imbalance will the nurse monitor for in this patient?

• A. Hypermagnesemia
• B. Hypernatremia
• C. Hypocalcemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Thiazide diuretics like hydrochlorothiazide can cause hypokalemia. Hypokalemia enhances the effects of digoxin, leading to digoxin toxicity. Thiazides can also cause hypercalcemia. Choices A, B, and C are incorrect. Hypermagnesemia is not typically associated with hydrochlorothiazide use. Hypernatremia and hypocalcemia are not the primary electrolyte imbalances to monitor for in this scenario.
