1. A patient with asthma is prescribed a corticosteroid inhaler. What is the most important instruction to give to the patient?
- A. Use the inhaler only during asthma attacks.
- B. Rinse the mouth after using the inhaler.
- C. Take a double dose if symptoms worsen.
- D. Avoid using a spacer with the inhaler.
Correct answer: B
Rationale: The most important instruction to give to a patient using a corticosteroid inhaler is to rinse the mouth after each use. This is crucial to prevent the development of oral thrush, a common side effect of corticosteroid inhalers. Failure to rinse the mouth can lead to the overgrowth of yeast in the mouth, causing oral thrush, which can be uncomfortable and require additional treatment. Therefore, reminding patients to rinse their mouth after using the inhaler is essential in preventing this potential complication. Choices A, C, and D are incorrect. Using the inhaler only during asthma attacks may lead to uncontrolled asthma symptoms. Taking a double dose without healthcare provider instruction can result in overdose or side effects. Avoiding a spacer with the inhaler can reduce the effectiveness of delivering the medication to the lungs.
2. When providing dietary instructions to a client with cirrhosis, which dietary restriction is important for the nurse to emphasize?
- A. Low-protein diet
- B. Low-sodium diet
- C. High-fiber diet
- D. High-calcium diet
Correct answer: B
Rationale: A low-sodium diet is crucial for clients with cirrhosis to manage fluid retention and ascites. Excessive sodium intake can worsen fluid accumulation in the body, leading to complications. By restricting sodium intake, the client can help reduce fluid retention and maintain better overall health. Therefore, emphasizing a low-sodium diet is essential in the dietary management of cirrhosis. Choices A, C, and D are not the primary focus for cirrhosis management. While protein restriction may be necessary in advanced stages of liver disease, it is not the main dietary concern in cirrhosis. High-fiber and high-calcium diets are generally beneficial for overall health but are not specifically emphasized in cirrhosis management.
3. The sister of a patient diagnosed with BRCA gene-related breast cancer asks the nurse, 'Do you think I should be tested for the gene?' Which response by the nurse is most appropriate?
- A. In most cases, breast cancer is not caused by the BRCA gene.
- B. It depends on how you will feel if the test is positive for the BRCA gene.
- C. There are many things to consider before deciding to have genetic testing.
- D. You should decide first whether you are willing to have a bilateral mastectomy.
Correct answer: C
Rationale: The most appropriate response by the nurse is C: 'There are many things to consider before deciding to have genetic testing.' Genetic testing for BRCA gene mutations is a complex decision that involves various factors such as emotional readiness, potential impact on insurance and employability, and the implications of test results. Option A is incorrect because although most breast cancers are not related to BRCA gene mutations, individuals with these mutations have a significantly higher risk. Option B is not ideal as it oversimplifies the decision-making process by focusing solely on emotional aspects. Option D is incorrect as it implies a predetermined course of action (mastectomy) before even undergoing genetic testing, which is not appropriate.
4. A client with a new diagnosis of diabetes mellitus is learning to self-administer insulin. Which instruction should the nurse include?
- A. Store the insulin in the freezer.
- B. Administer the insulin at the same site each time.
- C. Rotate injection sites within the same region.
- D. Shake the vial vigorously before drawing up the insulin.
Correct answer: C
Rationale: The correct instruction for a client learning to self-administer insulin is to rotate injection sites within the same region. This practice helps prevent lipodystrophy, which is a condition characterized by fat tissue changes due to repeated injections in the same spot, and also ensures consistent absorption of insulin throughout the body. Storing insulin in the freezer is incorrect as it can lead to denaturation of the insulin. Administering the insulin at the same site each time can cause lipodystrophy and inconsistent absorption. Shaking the vial vigorously before drawing up the insulin is also incorrect as it can lead to insulin degradation.
5. Why is morphine administered to a patient with a myocardial infarction (MI)?
- A. To reduce pain.
- B. To decrease anxiety.
- C. To reduce cardiac workload.
- D. To increase respiratory rate.
Correct answer: C
Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.
