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. A healthcare provider calls a physician with the concern that a patient has developed a pulmonary embolism. Which of the following symptoms has the healthcare provider most likely observed?

• A. The patient is somnolent with decreased response to stimuli.
• B. The patient suddenly complains of chest pain and shortness of breath.
• C. The patient has developed a wet cough and the healthcare provider hears crackles on auscultation of the lungs.
• D. The patient has a fever, chills, and loss of appetite.

Correct answer: B

Rationale: The correct answer is 'The patient suddenly complains of chest pain and shortness of breath.' Typical symptoms of pulmonary embolism include chest pain, shortness of breath, and severe anxiety. The physician should be notified immediately. Clinical signs and symptoms for pulmonary embolism are nonspecific; therefore, patients suspected of having pulmonary embolism"?because of unexplained dyspnea, tachypnea, or chest pain or the presence of risk factors for pulmonary embolism"?must undergo diagnostic tests until the diagnosis is ascertained or eliminated or an alternative diagnosis is confirmed. Choices A, C, and D describe symptoms that are not typically associated with a pulmonary embolism, making them incorrect.

3. A nurse and client are discussing the client's progress toward understanding his behavior under stress. This is typical of which phase in the therapeutic relationship?

• A. Pre-interaction
• B. Orientation
• C. Working
• D. Termination

Correct answer: C

Rationale: The correct answer is the working phase. During this phase, the nurse and client actively work together to explore alternative behaviors and techniques. Discussions in this phase focus on understanding the underlying meaning behind the behavior and implementing strategies for change. Pre-interaction (choice A) refers to the phase before the nurse and client first meet and establish a relationship. The orientation phase (choice B) involves introductions, setting goals, and establishing boundaries. Termination (choice D) is the phase where the therapeutic relationship concludes, and closure is achieved.

4. The nurse is preparing to administer an enteral feeding to a client via a nasogastric feeding tube. The most important action of the nurse is:

• A. Verify correct placement of the tube
• B. Check that the feeding solution matches the dietary order
• C. Aspirate gastric contents to determine the amount of the last feeding remaining in the stomach
• D. Ensure that the feeding solution is at room temperature

Correct answer: A

Rationale: The most crucial action for the nurse when preparing to administer enteral feeding via a nasogastric tube is to verify the correct placement of the tube. Proper placement of the tube is vital to prevent complications such as aspiration into the lungs. The definitive methods to confirm the position of the nasogastric tube include visualization through an x-ray or aspirating stomach contents and checking their pH (usually pH 1 to 5). Aspirated stomach content can also be tested for bilirubin to confirm placement in the stomach. Choice B, checking that the feeding solution matches the dietary order, is important for ensuring the correct nutrition is provided but is not as critical as verifying tube placement to prevent potential harm. Choice C, aspirating gastric contents to determine the amount of the last feeding remaining in the stomach, is a common nursing practice but is not the most crucial action when compared to ensuring correct tube placement. Choice D, ensuring that the feeding solution is at room temperature, is relevant for patient comfort and preventing thermal injury but is not as essential as confirming correct tube placement to prevent serious complications.

5. The nurse is caring for an infant with cryptorchidism. The nurse anticipates that the most likely diagnostic study to be prescribed would be the one that assesses which item?

• A. Babinski reflex
• B. DNA synthesis
• C. Urinary function
• D. Chromosomal analysis

Correct answer: C

Rationale: Cryptorchidism, also known as undescended testes, may be caused by hormonal deficiency, intrinsic testicular abnormality, or a structural problem. Diagnostic studies for cryptorchidism typically involve assessing urinary function because the kidneys and testes originate from the same embryonic tissue. The Babinski reflex is a test for neurological function and is not relevant to evaluating cryptorchidism. DNA synthesis and chromosomal analysis are not commonly used diagnostic tests for cryptorchidism, as they are unrelated to the disorder's etiology or presentation.
