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. The nurse is teaching a client about the administration of a subcutaneous injection. Which site is most appropriate for this type of injection?
- A. Deltoid muscle
- B. Dorsogluteal muscle
- C. Ventrogluteal muscle
- D. Abdomen
Correct answer: D
Rationale: The abdomen is a common site for subcutaneous injections due to its accessibility and ample subcutaneous tissue. Subcutaneous injections are typically given in areas with a layer of fat between the skin and muscle, such as the abdomen, to allow for slow and consistent absorption of the medication. The deltoid muscle is more appropriate for intramuscular injections, not subcutaneous. The dorsogluteal muscle and ventrogluteal muscle are also more suited for intramuscular injections, not subcutaneous.
3. What is the most important aspect of colostomy care to teach the client?
- A. Change the colostomy bag daily
- B. Irrigate the colostomy daily
- C. Avoid high-fiber foods
- D. Assess the stoma for color and swelling
Correct answer: D
Rationale: The most crucial aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is essential to detect early signs of complications such as ischemia or infection. Changing the colostomy bag daily is important but not as critical as assessing the stoma for complications. Irrigating the colostomy daily is not a standard recommendation and should be performed based on healthcare provider's instructions. While avoiding high-fiber foods may be beneficial for some individuals with a colostomy, it is not the most important aspect of care compared to monitoring the stoma for complications.
4. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?
- A. Check blood pressure.
- B. Assess heart rate.
- C. Monitor respiratory rate.
- D. Measure oxygen saturation.
Correct answer: B
Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.
5. A client with a history of chronic obstructive pulmonary disease (COPD) is prescribed oxygen therapy at 2 liters per minute via nasal cannula. What is the most important instruction the nurse should provide?
- A. Increase the oxygen flow rate if shortness of breath occurs
- B. Use oxygen only when experiencing shortness of breath
- C. Do not adjust the oxygen flow rate without consulting a healthcare provider
- D. Use a humidifier with the oxygen to prevent dry mucous membranes
Correct answer: C
Rationale: The most important instruction the nurse should provide to a client with COPD prescribed oxygen therapy is not to adjust the oxygen flow rate without consulting a healthcare provider. This is crucial because too much oxygen can suppress the client's respiratory drive, leading to further complications. Choice A is incorrect because increasing the oxygen flow rate without medical advice can be harmful. Choice B is incorrect as oxygen therapy should be used as prescribed, not just when symptoms occur. Choice D is incorrect as the priority is to ensure the correct oxygen flow rate rather than using a humidifier.
