Adult Health Exam 1
1. The healthcare provider prescribes erythromycin (Ilosone) 300 mg PO QID. The medication label reads, 'Ilosone 100mg/5mL.' How many mL should the nurse administer at each dose?
- A. 15 mL
- B. 10 mL
- C. 20 mL
- D. 5 mL
Correct answer: A
Rationale: To determine the volume of medication needed for a 300 mg dose of Ilosone (100mg/5mL), we set up a proportion: 100 mg is to 5 mL as 300 mg is to x mL. Cross-multiplying, we get x = (300*5)/100 = 15 mL. Therefore, the nurse should administer 15 mL at each dose. Choice B (10 mL) is incorrect as it does not reflect the correct calculation based on the medication concentration. Choices C (20 mL) and D (5 mL) are also incorrect as they do not accurately calculate the volume required for the prescribed dose.
2. During a severe asthma exacerbation in a client, what is the nurse's priority?
- A. Administer a rescue inhaler immediately
- B. Prepare for intubation
- C. Encourage deep breathing exercises
- D. Monitor oxygen saturation levels
Correct answer: A
Rationale: During a severe asthma exacerbation, the nurse's priority is to administer a rescue inhaler immediately. This action helps open the airways and improve breathing, which is crucial in managing the exacerbation. Choice B, preparing for intubation, would be considered if the client's condition deteriorates and they are unable to maintain adequate oxygenation even after using the rescue inhaler. Encouraging deep breathing exercises (Choice C) may not be appropriate during a severe exacerbation as the client may struggle to breathe. While monitoring oxygen saturation levels (Choice D) is important, the immediate administration of a rescue inhaler takes precedence to address the acute breathing difficulty.
3. A client with a history of chronic heart failure is admitted with symptoms of dyspnea and fatigue. What initial intervention should the nurse prepare to implement?
- A. Administration of IV diuretics
- B. Oxygen therapy
- C. Bed rest
- D. Dietary consultation
Correct answer: B
Rationale: The correct initial intervention for a client with chronic heart failure presenting with dyspnea and fatigue is oxygen therapy. Oxygen therapy can help relieve dyspnea and improve oxygen saturation levels, which are crucial in managing heart failure exacerbations. Administering IV diuretics may be necessary later to address fluid overload, but oxygen therapy takes precedence in addressing the immediate respiratory distress. Bed rest and dietary consultation are important aspects of care for heart failure patients, but in this scenario, oxygen therapy is the priority to improve the client's respiratory status.
4. The healthcare provider is assessing a client with a suspected diagnosis of appendicitis. Which symptom is most indicative of this condition?
- A. Right upper quadrant pain
- B. Nausea and vomiting
- C. Rebound tenderness at McBurney's point
- D. Hematuria
Correct answer: C
Rationale: Rebound tenderness at McBurney's point is a classic sign of appendicitis. This symptom is due to irritation of the peritoneum when pressure is released during palpation. Right upper quadrant pain (Choice A) is more commonly associated with gallbladder issues. Nausea and vomiting (Choice B) can occur in various abdominal conditions and are not specific to appendicitis. Hematuria (Choice D) is the presence of blood in the urine and is not a typical symptom of appendicitis.
5. What is the primary function of neutrophils?
- A. Heparin secretion
- B. Transport oxygen
- C. Phagocytotic action
- D. Antibody formation
Correct answer: C
Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
