1. The test used to differentiate sickle cell trait from sickle cell disease is:

• A. Sickle cell preparation.
• B. Peripheral smear.
• C. Sickledex.
• D. Hemoglobin electrophoresis

Correct answer: D

Rationale: The correct test to differentiate between sickle cell trait and sickle cell disease is hemoglobin electrophoresis. This test separates different types of hemoglobin based on their electrical charge, allowing for the identification of specific hemoglobin variants like HbS in sickle cell disease. Sickle cell preparation and Sickledex are not specific tests for this differentiation. While a peripheral smear can show sickle cells, it does not provide a definitive differentiation between the trait and the disease as it doesn't identify the specific hemoglobin variant present.

2. A client was involved in a motor vehicle accident in which the seat belt was not worn. The client is exhibiting crepitus, decreased breath sounds on the left, complains of shortness of breath, and has a respiratory rate of 34/min. Which of the following assessment findings should concern the nurse the most?

• A. temperature of 102�F and a productive cough
• B. arterial blood gases (ABGs) with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg
• C. trachea deviating to the right
• D. barrel-chested appearance

Correct answer: C

Rationale: The correct answer is 'trachea deviating to the right.' A mediastinal shift is indicative of a tension pneumothorax, which is a dangerous complication seen in trauma patients with symptoms like crepitus, decreased breath sounds, shortness of breath, and tachypnea. Assessing for acute traumatic injuries is crucial in this context. Choice A, a temperature of 102�F and a productive cough, is common in pneumonia cases and not as concerning as a mediastinal shift. Choice B, ABGs with a PaO2 of 92 mmHg and PaCO2 of 40 mmHg, shows values within normal limits and does not suggest a tension pneumothorax. Choice D, a barrel-chested appearance, is typical of COPD and not directly related to the acute traumatic injury described. A tension pneumothorax is a medical emergency where air cannot escape the pleural cavity, leading to lung collapse and a mediastinal shift to the unaffected side with a downward displacement of the diaphragm.

3. At what age will vision be 20/20 in children?

• A. 4 years old
• B. 5 years old
• C. 6 years old
• D. 7 years old

Correct answer: C

Rationale: The correct answer is 6 years old. At this age, children typically have the potential for 20/20 vision. This is considered the standard age for achieving optimal vision clarity. Choices A, B, and D are incorrect as they are not typically associated with the age at which children achieve 20/20 vision.

4. In the treatment of symptomatic bradycardia, which medication is most commonly recognized?

• A. Questran
• B. Digitalis
• C. Nitroglycerin
• D. Atropine

Correct answer: D

Rationale: Atropine is the medication most commonly recognized for the treatment of symptomatic bradycardia because it increases the rate of conduction in the AV node, helping to alleviate bradycardia. Questran is a medication used to lower cholesterol levels and is not indicated for bradycardia. Digitalis, such as Digoxin, is used for heart failure and atrial fibrillation but not typically for bradycardia. Nitroglycerin is primarily used for angina and not bradycardia.

5. A nurse is instructing a patient about the warning signs of Digitalis side effects. Which of the following side effects should the nurse tell the patient are sometimes associated with excessive levels of Digitalis?

• A. Seizures
• B. Muscle weakness
• C. Depression
• D. Anxiety

Correct answer: B

Rationale: The correct answer is 'Muscle weakness.' Palpitations and muscle weakness are commonly associated with excessive levels of Digitalis. Seizures, depression, and anxiety are not typically linked to Digitalis toxicity. Seizures could be more related to other medications or conditions, while depression and anxiety are not commonly reported side effects of Digitalis.
