NCLEX PN Exam Cram
1. A healthcare professional is reviewing a patient's ECG report. The patient exhibits a flat T wave, depressed ST segment, and short QT interval. Which of the following medications can cause all of the above effects?
- A. Morphine
- B. Atropine
- C. Procardia
- D. Digitalis
Correct answer: D
Rationale: The correct answer is Digitalis. Digitalis is known to cause a flat T wave, depressed ST segment, and a short QT interval on an ECG report. These ECG changes are characteristic of digitalis toxicity. Morphine is not typically associated with these ECG changes. Atropine is more commonly linked to increasing heart rate rather than causing these specific ECG abnormalities. Procardia is a calcium channel blocker that does not typically produce the described ECG findings. Therefore, Digitalis is the most likely medication causing these effects in the patient.
2. A patient has a history of cardiac arrhythmia. A nurse has been ordered to give 2 units of blood to this patient. The nurse should take which of the following actions?
- A. Administer pain medication to the patient.
- B. Inform the patient's family about the procedure in person.
- C. Decrease the temperature of the blood to be given.
- D. Increase the temperature of the blood to be given.
Correct answer: D
Rationale: In patients with a history of cardiac arrhythmia, warming the blood before transfusion can help prevent additional arrhythmias. Cold blood can lead to arrhythmias and should be avoided. Administering pain medication (Choice A) is not directly related to the safe administration of blood. Informing the patient's family in person (Choice B) is important but not the immediate action required for safe transfusion. Decreasing the temperature of the blood to be given (Choice C) would increase the risk of cardiac arrhythmia, contrary to the goal of ensuring patient safety.
3. A client has been receiving cyanocobalamin (B12) injections for the past 6 weeks. Which laboratory finding indicates that the medication is having the desired effect?
- A. Neutrophil count of 60%
- B. Basophil count of 0.5%
- C. Monocyte count of 2%
- D. Reticulocyte count of 1%
Correct answer: D
Rationale: Cyanocobalamin is a B12 medication used for pernicious anemia. A reticulocyte count of 1% indicates the desired effect of the medication, as reticulocytes are immature red blood cells that increase in response to B12 therapy, improving anemia. Neutrophils, basophils, and monocytes are white blood cells and are not directly influenced by B12 injections, making them incorrect choices.
4. A person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?
- A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
- B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
- C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
- D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
Correct answer: A
Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.
5. The client is scheduled for surgical repair of a detached retina. What is the most likely preoperative nursing diagnosis for this client?
- A. Anxiety related to loss of vision and potential failure to regain vision.
- B. Deficient knowledge (preoperative and postoperative activities) related to lack of information.
- C. Acute pain related to tissue injury and decreased circulation to the eye.
- D. Risk for infection related to the eye injury.
Correct answer: A
Rationale: The correct preoperative nursing diagnosis for a client scheduled for surgical repair of a detached retina is 'Anxiety related to loss of vision and potential failure to regain vision.' A client facing the threat of permanent blindness due to a detached retina is likely to experience anxiety. Addressing this anxiety is crucial before providing education, as severe anxiety can hinder the client's ability to absorb new information. The nurse should offer emotional support, encourage the client to express concerns, and clarify any misconceptions. Acute pain is not a typical symptom of a detached retina, and the risk of infection preoperatively is minimal, making choices C and D less relevant in this scenario.
