A client diagnosed with systemic lupus erythematosus (SLE) comes to the emergency department with severe back pain. She reports that she first felt pain after manually opening her garage door and that she is taking prednisone daily. When adverse effect of long-term corticosteroid therapy is most likely responsible for the pain?
- A. Hypertension
- B. Muscle wasting
- C. Osteoporosis
- D. Truncal obesity
Correct Answer: C
Rationale: Osteoporosis is the most likely adverse effect of long-term corticosteroid therapy responsible for the severe back pain experienced by the client with systemic lupus erythematosus (SLE). Corticosteroids such as prednisone can lead to bone resorption and calcium loss, resulting in weakened bones and increased risk of fractures. Back pain in this case could be a sign of vertebral compression fractures due to osteoporosis induced by prolonged corticosteroid use. It is important for healthcare providers to monitor bone health in patients on long-term corticosteroid therapy and consider strategies to prevent or manage osteoporosis.
all the following are major signs of DM except :
- A. polydipsia
- B. hypernatremia
- C. polyphagia
- D. hyporeflexia and bradycardia
Correct Answer: D
Rationale: Hyporeflexia (reduced deep tendon reflexes) and bradycardia (slow heart rate) are not typical signs of diabetes mellitus (DM). The major signs of DM are the classic "3 Ps": polydipsia (excessive thirst), polyuria (excessive urination), and polyphagia (excessive hunger). These symptoms are usually due to elevated blood glucose levels leading to increased thirst, frequent urination, and hunger. Additionally, unexplained weight loss can also be a common symptom of DM. Other complications related to DM, such as neuropathy, can lead to issues like hyporeflexia, but they are not considered major signs of DM itself.
A nurse is preparing to administer an oral iron supplement to a hospitalized infant. Which should not be given simultaneously with the iron supplement?
- A. Milk
- B. Multivitamin
- C. Fruit juice
- D. Meat, fish, poultry
Correct Answer: A
Rationale: Milk should not be given simultaneously with an oral iron supplement because calcium in milk can interfere with the absorption of iron. Calcium competes with iron for absorption in the digestive tract, thereby reducing the absorption of iron when both are taken together. It is advisable to wait at least 1-2 hours after giving the iron supplement before offering milk to ensure optimal absorption of iron. This is a common practice to improve iron absorption and prevent any potential decrease in the effectiveness of the iron supplement.
Clay is an 8-year-old boy diagnosed with heart failure. Which of the following shows that he is strictly following the directed therapeutic regimen?
- A. Daily use of an antibiotic
- B. Pulse rate less than 50 beats/minute
- C. Normal weight for age
- D. Elevation in red blood cell (RBC) count
Correct Answer: C
Rationale: In a young child like Clay who is diagnosed with heart failure, following the directed therapeutic regimen would involve maintaining a normal weight for his age. Weight monitoring is crucial in managing heart failure as excessive weight gain could lead to worsening of symptoms and complications. Ensuring that Clay stays within a normal weight range for his age shows his adherence to dietary recommendations, fluid restrictions, and overall treatment plan aimed at managing his heart failure effectively. Monitoring his weight would also help healthcare providers assess if the treatment plan is working and make necessary adjustments as needed. Therefore, Clay maintaining a normal weight for his age indicates that he is strictly following the directed therapeutic regimen for his heart failure.
A 50-year-old African American patient is diagnosed with anemia. Where can the nurse assess for pallor?
- A. Scalp
- B. Chest
- C. Axillae
- D. Conjunctivae
Correct Answer: D
Rationale: When assessing for pallor in a patient with anemia, the nurse should specifically look at the conjunctivae (the membranes that cover the white part of the eyes). In individuals with anemia, the lack of red blood cells can result in paleness in the conjunctivae, which can be observed as a pale or whitish color. This area is especially useful for assessing pallor in individuals with darker skin tones, such as African Americans, where pallor may be less noticeable on other areas of the body.
