The nurse is preparing to initiate an intravenous nitroglycerin drip on a client who has experienced an acute myocardial infarction. In the absence of an invasive (arterial) monitoring line, the nurse prepares to have which piece of equipment for use at the bedside to help assure the client's safety?
- A. Defibrillator
- B. Pulse oximeter
- C. Central venous pressure (CVP) tray
- D. Noninvasive blood pressure monitor
Correct Answer: D
Rationale: Nitroglycerin dilates arteries and veins (vasodilator), causing peripheral blood pooling, thus reducing preload, afterload, and myocardial workload. This action accounts for the primary side effect of nitroglycerin, which is hypotension. In the absence of an arterial monitoring line, the nurse should have a noninvasive blood pressure monitor for use at the bedside.

The nurse assesses a peripheral intravenous (IV) dressing and notes that it is damp and the tape is loose. What action should the nurse take initially?
- A. Stop the infusion immediately.
- B. Apply a sterile, occlusive dressing.
- C. Ensure all IV tubing connections are tight.
- D. Gather the supplies needed to insert a new IV.
Correct Answer: C
Rationale: To determine subsequent nursing interventions, the nurse checks all connections to ensure tight seals while the IV infuses to help locate the source of the leak. If the leak is at the insertion site, the nurse stops the infusion, removes the IV, and inserts a new IV catheter. The nurse applies a new sterile occlusive dressing after resolving the source of the leak.
A client who experienced repeated pleural effusions from inoperable lung cancer is to undergo pleurodesis. What intervention should the nurse plan to implement after the primary health care provider injects the sclerosing agent through the chest tube to help assure the effectiveness of the procedure?
- A. Ambulate the client.
- B. Clamp the chest tube.
- C. Ask the client to cough and deep breathe.
- D. Ask the client to remain in a side-lying position.
Correct Answer: B
Rationale: After injection of the sclerosing agent, the chest tube is clamped to prevent the agent from draining back out of the pleural space. Depending on primary health care provider preference, a repositioning schedule is used to disperse the substance. Ambulation, coughing, and deep breathing have no specific purpose in the immediate period after injection.
The nurse sends a sputum specimen to the laboratory for culture from a client with suspected active tuberculosis (TB). The results report that Mycobacterium tuberculosis is cultured. How should the nurse correctly analyze these results?
- A. The results are positive for active tuberculosis.
- B. The results indicate a less virulent strain of tuberculosis.
- C. The results are inconclusive until a repeat sputum specimen is sent.
- D. The results are unreliable unless the client has also had a positive tuberculin skin test (TST).
Correct Answer: A
Rationale: Culture of Mycobacterium tuberculosis from sputum or other body secretions or tissue confirms the diagnosis of active tuberculosis.
The nurse is reviewing the record of a client with a disorder involving the inner ear. Which finding should the nurse most likely note as an assessment finding in this client?
- A. Tinnitus
- B. Burning in the ear
- C. Itching in the affected ear
- D. Severe pain in the affected ear
Correct Answer: A
Rationale: Tinnitus is the most common complaint of clients with ear disorders, especially disorders involving the inner ear. Manifestations of tinnitus can range from mild ringing in the ear that can go unnoticed during the day to a loud roaring in the ear that can interfere with the client's thinking process and attention span. The assessment findings noted in options 2, 3, and 4 are not specifically noted in the client with an inner ear disorder.
The nurse instructs a mother of a child who had a plaster cast applied to the arm about measures that will help the cast dry. Which instructions should the nurse provide to the mother? Select all that apply.
- A. Lift the cast using the fingertips.
- B. Place the child on a firm mattress.
- C. Direct a fan toward the cast to facilitate drying.
- D. Support the cast and adjacent joints with pillows.
- E. Place the extremity with the cast in a dependent position.
- F. Reposition the extremity with the cast every 2 to 4 hours.
Correct Answer: B,C,D,F
Rationale: To help the cast dry, the child should be placed on a firm mattress. A fan may be directed toward the cast to facilitate drying. Once the cast is dry, the cast should sound hollow and be cool to touch. The cast and adjacent joints should be elevated and supported with pillows. To ensure thorough drying, the extremity with the cast should be repositioned every 2 to 4 hours. The cast is lifted by using the palms of the hands (not the fingertips) to prevent indentation in the wet cast surface. Indentations could possibly cause pressure on the skin under the cast.
