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. Which of the following terms refers to soft tissue injury caused by blunt force?

• A. contusion
• B. strain
• C. sprain
• D. dislocation

Correct answer: A

Rationale: A contusion is a soft tissue injury caused by blunt force. It is an injury that does not break the skin, caused by a blow, and characterized by swelling, discoloration, and pain. The immediate application of cold might limit the development of a contusion. A strain is a muscle pull from overuse, overstretching, or excessive stress. A sprain is caused by a wrenching or twisting motion. A dislocation is a condition where the articular surfaces of the bones forming a joint are no longer in anatomical contact. Therefore, the correct answer is 'contusion' as it specifically relates to soft tissue injury caused by blunt force.

3. What is an appropriate intervention for the client with suspected genitourinary trauma and visible blood at the urethral meatus?

• A. Insertion of a Foley catheter.
• B. Performing an in-and-out catheter specimen for urinalysis.
• C. Obtaining a voided urine specimen for urinalysis.
• D. Ordering a urinalysis by the physician.

Correct answer: D

Rationale: When a client presents with suspected genitourinary trauma and visible blood at the urethral meatus, obtaining a voided urine specimen for urinalysis is an appropriate intervention. This helps assess for any urinary tract injuries or abnormalities without further traumatizing the area. Insertion of a Foley catheter (Choice A) should be avoided as it can worsen the existing trauma. Performing an in-and-out catheter specimen (Choice B) involves unnecessary manipulation and can increase the risk of complications. Ordering a urinalysis by the physician (Choice D) may delay the assessment compared to obtaining a direct voided urine specimen.

4. What is the drug of choice for herpes simplex virus 1, herpes simplex virus 2, and varicella-zoster virus?

• A. HIV.
• B. HSV 1, HSV 2, and VZV.
• C. CMV
• D. Influenza A viruses.

Correct answer: B

Rationale: Acyclovir (Zovirax) is the drug of choice for herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), and varicella-zoster virus (VZV) infections. It works by inhibiting viral DNA replication. Acyclovir is excreted unchanged in the urine, so caution is needed in renal impairment. Choice A, HIV, is incorrect as acyclovir is not the drug of choice for HIV. Choice C, CMV, is incorrect as acyclovir is not the preferred treatment for cytomegalovirus (CMV) infections. Choice D, Influenza A viruses, is incorrect as acyclovir is not used to treat influenza viruses.

5. How can a diet high in fiber content benefit an individual?

• A. aid in weight loss.
• B. reduce diabetic ketoacidosis.
• C. lower cholesterol.
• D. reduce the need for folate.

Correct answer: C

Rationale: A diet high in fiber content can help lower cholesterol levels by reducing the absorption of cholesterol in the bloodstream. Fiber-rich foods, like grains, apples, potatoes, and beans, can aid in this process. While fiber can aid in weight loss by promoting a feeling of fullness and aiding digestion, it is not primarily for fast weight loss. Fiber does not directly reduce the risk of diabetic ketoacidosis, which is more related to managing blood sugar levels through insulin therapy and dietary control. Folate is a B vitamin that is essential for various bodily functions and is not influenced by fiber intake. Therefore, the correct answer is to lower cholesterol, as fiber plays a significant role in this benefit.
