Nursing Elites

1. The nurse is reviewing the lab results of a patient taking lithium for schizoaffective disorder. The lab results show that the blood lithium value is 1.7 mcg/L. What would the nurse take as the priority action?

• A. Induce vomiting
• B. Hold the next dose of Lithium
• C. Administer an antiemetic
• D. Give the next dose of Lithium

Correct answer: B

Rationale: The correct answer is to hold the next dose of Lithium. The blood lithium value of 1.7 mcg/L exceeds the therapeutic range of 0.5-1.5 mcg/L, indicating potential toxicity. Holding the next dose is crucial to prevent further accumulation of lithium in the bloodstream. Inducing vomiting is not appropriate in this situation as the priority is to prevent further absorption of lithium. Administering an antiemetic is not the priority in lithium toxicity. Giving the next dose of lithium would exacerbate the toxicity and should be avoided.

2. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

• A. Start an IV so contrast media may be given
• B. Ensure that the patient has been NPO for at least 6 hours.
• C. Inform radiology that a radioactive glucose preparation is needed
• D. Instruct the patient to undress to the waist and remove any metal objects

Correct answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

3. Which laboratory test result should the nurse monitor to evaluate the effects of therapy for a 62-year-old female patient with acute pancreatitis?

• A. Calcium
• B. Bilirubin
• C. Amylase
• D. Potassium

Correct answer: C

Rationale: The correct answer is C: Amylase. In acute pancreatitis, amylase levels are typically elevated. Monitoring amylase levels helps assess the effectiveness of therapy in managing the condition. Elevated amylase is a key indicator of pancreatic inflammation. Calcium (Choice A) levels may be affected in pancreatitis, but they are not the primary indicator for evaluating therapy effectiveness. Bilirubin (Choice B) and Potassium (Choice D) levels may also be altered in pancreatitis, but they are not specific markers for monitoring therapy response in acute pancreatitis.

4. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client

• A. Has increased airway obstruction
• B. Has improved airway obstruction
• C. Needs to be suctioned
• D. Exhibits hyperventilation

Correct answer: B

Rationale: The higher pitched a sound is, the more narrow the airway. Therefore, the obstruction has increased or worsened. With no evidence of secretions, there is no support to indicate the need for suctioning. Wheezes changing from low-pitched to high-pitched and extending throughout exhalation suggest a progression in airway constriction, indicating an increase in airway obstruction. Option B is incorrect because the change in wheezes from low to high pitch does not suggest an improvement in airway obstruction. Option C is incorrect as there is no indication of secretions requiring suctioning. Option D is incorrect as hyperventilation is not typically associated with the described change in wheezes.

5. While caring for the client during the first hour after delivery, the nurse determines that the uterus is boggy and there is vaginal bleeding. What should be the nurse's first action?

• A. Check vital signs
• B. Massage the fundus
• C. Offer a bedpan
• D. Check for perineal lacerations

Correct answer: B

Rationale: Massage the fundus. The nurse's first action should be to massage the fundus until it is firm as uterine atony is the primary cause of bleeding in the first hour after delivery. Checking vital signs, offering a bedpan, or checking for perineal lacerations are important assessments but addressing the boggy uterus and vaginal bleeding due to uterine atony takes precedence in this situation.
