1. 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.

2. A caregiver is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The caregiver asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the caregiver make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.

3. A healthcare provider is caring for a group of clients. Which of the following clients is not at risk for pulmonary embolism?

• A. A client who has a BMI of 30
• B. A female client who is postmenopausal
• C. A client who has a fractured femur
• D. A client who has chronic atrial fibrillation

Correct answer: B

Rationale: Postmenopausal status is not a significant risk factor for pulmonary embolism. Risk factors for pulmonary embolism include obesity (BMI of 30 or higher), immobility such as having a fractured femur, and conditions like chronic atrial fibrillation that increase the risk of blood clot formation. While postmenopausal status may be associated with other health risks, it is not directly linked to an increased risk of pulmonary embolism.

4. A client with active tuberculosis is prescribed isoniazid, rifampin, pyrazinamide, and ethambutol. Which statement by the client indicates an understanding of the teaching?

• A. I can substitute one medication for another if I run out because they all fight infection.
• B. I will wash my hands each time I cough.
• C. I am glad I don't have to have any more sputum specimens.
• D. I don't need to worry about where I go once I start taking my medications.

Correct answer: B

Rationale: The correct statement indicating understanding of tuberculosis medication regimen is 'I will wash my hands each time I cough.' This statement shows knowledge of infection control practices to prevent the spread of tuberculosis. Washing hands after coughing helps in reducing the transmission of the disease to others. The other options are incorrect. Option A is incorrect as each medication in the regimen has a specific role, and substituting one for another can compromise the effectiveness of treatment. Option C is incorrect as obtaining sputum specimens is essential for monitoring treatment response. Option D is incorrect as the client should still adhere to infection control measures and avoid exposing others to tuberculosis.

5. When caring for a toddler with acute lymphocytic leukemia, in which of the following activities should the toddler participate?

• A. Looking at alphabet flashcards.
• B. Playing with a large plastic truck.
• C. Using scissors to cut out paper shapes.
• D. Watching a cartoon in the dayroom.

Correct answer: B

Rationale: Toddlers with acute lymphocytic leukemia may have compromised immune systems and need to avoid activities that increase infection risk. Playing with a large plastic truck is a safe and engaging activity that does not pose a high risk of infection. This choice also promotes physical activity and creativity, which are beneficial for a toddler's development during illness.
