Nursing Elites

1. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.

2. During an assessment of a client with cardiomyopathy, the nurse finds that the systolic blood pressure has decreased from 145 to 110 mm Hg and the heart rate has risen from 72 to 96 beats per minute, and the client complains of periodic dizzy spells. The nurse instructs the client to:

• A. Increase fluids that are high in protein
• B. Restrict fluids
• C. Force fluids and reassess blood pressure
• D. Limit fluids to non-caffeine beverages

Correct answer: D

Rationale: In this scenario, the client with cardiomyopathy is exhibiting signs of orthostatic hypotension, which is characterized by a significant drop in systolic blood pressure (>15 mm Hg) and an increase in heart rate (>15%), along with dizziness. These symptoms suggest volume depletion, inadequate vasoconstrictor mechanisms, and autonomic insufficiency. The appropriate nursing intervention in this case is to force fluids and reassess blood pressure to address the underlying issue of volume depletion and improve hemodynamic stability. Choices A, B, and D are incorrect because increasing fluids high in protein, restricting fluids, or limiting fluids to non-caffeine beverages are not appropriate actions for a client experiencing orthostatic hypotension and signs of volume depletion.

3. What is the most common complication of chest wall injury?

• A. Hemothorax
• B. Atelectasis
• C. Pneumonia
• D. Pneumothorax

Correct answer: C

Rationale: Pneumonia is the most common complication of chest wall injury. Chest wall trauma can lead to impaired lung function, making patients more susceptible to pneumonia due to reduced ability to clear secretions and impaired breathing. While hemothorax and pneumothorax are potential complications of chest wall injury, pneumonia is more commonly encountered. Atelectasis, although a common pulmonary complication, is not typically the most common complication seen in chest wall injuries.

4. Which of the following interventions should the nurse use when working with a Jackson-Pratt drain?

• A. Strip the tubing to remove clots by milking the tubing back toward the client
• B. Empty the drain when the amount of fluid reaches 25 cc
• C. Strip the tubing to remove clots by milking the tubing away from the client
• D. Maintain the level of the drain above the client's incision

Correct answer: C

Rationale: A Jackson-Pratt drain is a type of active wound drain that may be placed following a surgical procedure. This drain actively draws excess blood and fluid out of the wound. If clots develop within the tubing, the nurse should strip the tubing by milking it in a direction away from the client. This action helps to ensure the drain remains patent and effective. Option A is incorrect because the tubing should be milked away from the client, not towards. Option B is incorrect as the drain should be emptied based on the healthcare provider's orders, not at a fixed volume. Option D is incorrect because the level of the drain should be below the level of the incision to allow drainage by gravity.

5. The nurse is performing tuberculosis (TB) skin tests in a clinic that has many patients who have immigrated to the United States. Which question is most important for the nurse to ask before the skin test?

• A. Is there any family history of TB?
• B. How long have you lived in the United States?
• C. Do you take any over-the-counter (OTC) medications?
• D. Have you received the bacille Calmette-Guerin (BCG) vaccine for TB?

Correct answer: D

Rationale: It is crucial for the nurse to inquire about whether the patient has received the bacille Calmette-Guerin (BCG) vaccine for TB before performing the skin test. Patients who have received the BCG vaccine can have a positive Mantoux test, leading to the need for alternative screening methods, such as a chest x-ray, to determine TB infection. While family history of TB and length of time in the United States are relevant factors, they do not directly impact the decision to perform the TB skin test. Asking about over-the-counter medications, unless relevant to TB treatment, is not as critical as assessing BCG vaccination status.
