1. Which of the following interventions is considered the most effective form of universal precautions?
- A. Cap all used needles before removing them from their syringes
- B. Discard all used uncapped needles and syringes in an impenetrable protective container
- C. Wear gloves when administering IM injections
- D. Follow enteric precautions
Correct answer: B
Rationale: The most effective form of universal precautions is to discard all used uncapped needles and syringes in an impenetrable protective container. This practice minimizes the risk of needle-stick injuries, which are a significant concern when dealing with used needles. By safely disposing of uncapped needles, healthcare providers can protect themselves and others from potential exposure to bloodborne pathogens.
2. A healthcare provider is caring for an adolescent who has sickle-cell anemia. Which of the following manifestations indicates acute chest syndrome and should be immediately reported to the provider?
- A. Substernal retractions
- B. Hematuria
- C. Temperature 37.9°C (100.2°F)
- D. Sneezing
Correct answer: Substernal retractions
Rationale: Substernal retractions are a concerning sign of respiratory distress and can indicate acute chest syndrome, a severe complication of sickle-cell anemia. It results from vaso-occlusion in the pulmonary vasculature, leading to impaired oxygenation. Prompt reporting of this symptom is crucial for early intervention to prevent further complications. Hematuria, a high temperature, and sneezing are not specific manifestations of acute chest syndrome and would not warrant immediate notification to the provider in this context.
3. What is the best position for examining the rectum?
- A. Prone
- B. Sim's
- C. Knee-chest
- D. Lithotomy
Correct answer: C
Rationale: The knee-chest position is the most optimal position for examining the rectum. In this position, the patient kneels on the examination table with their chest resting on it, creating a straight line from the head to the lower back. This position allows for easier access and visualization of the rectal area, making it the preferred choice for rectal examinations. Prone position (choice A) is lying face down and is not ideal for rectal exams as it does not provide good access. Sim's position (choice B) is lying on the left side with the right knee and thigh flexed, also not ideal for rectal exams. Lithotomy position (choice D) is lying on the back with legs flexed and feet in stirrups, primarily used for gynecological exams and surgery, not for rectal examinations.
4. How many drops are equivalent to 1 tsp?
- A. 15
- B. 60
- C. 10
- D. 30
Correct answer: B
Rationale: 1 teaspoon (tsp) is equivalent to approximately 60 drops. Drops and teaspoons vary in volume and size, affecting the conversion ratio. Choice A (15 drops) is incorrect as it's a common misconception. Choice C (10 drops) and Choice D (30 drops) do not align with the standard conversion of 1 tsp to 60 drops.
5. Which hormone is secreted by the Islets of Langerhans?
- A. Progesterone
- B. Testosterone
- C. Insulin
- D. Hemoglobin
Correct answer: C
Rationale: Insulin is the correct answer. It is the hormone secreted by the Islets of Langerhans in the pancreas. These specialized cells regulate blood sugar levels by releasing insulin in response to high blood glucose levels. Insulin aids in glucose absorption by cells, lowering blood sugar levels. Progesterone, testosterone, and hemoglobin are not secreted by the Islets of Langerhans and do not play a role in blood sugar regulation.
