Question 1 of 5
A nurse is caring for a patient who is undergoing chemotherapy. Which intervention should be implemented to prevent infection?
Correct Answer: B
Rationale: The correct answer is B: Administer prophylactic antibiotics. This intervention helps prevent infection in the patient undergoing chemotherapy by targeting potential pathogens before they cause harm. Chemotherapy can weaken the immune system, making patients more susceptible to infections. Providing a mask (choice A) may help reduce exposure but does not directly address preventing infection. Repositioning the patient (choice C) is important for preventing complications like pressure ulcers but does not specifically target infection prevention. Performing a sputum culture (choice D) is useful for diagnosing respiratory infections but does not focus on preventing infections proactively. Administering prophylactic antibiotics is a targeted approach to reducing the risk of infection in immunocompromised patients.
Question 2 of 5
A 55-yr-old patient with increasing dyspnea is being evaluated for a possible diagnosis of chronic obstructive pulmonary disease (COPD). When teaching a patient about pulmonary spirometry for this condition, what is the most important question the nurse should ask?
Correct Answer: C
Rationale: The correct answer is C: Have you had frequent streptococcal throat infections? This is the most important question to ask because repeated streptococcal throat infections can lead to bronchiectasis, which is a risk factor for COPD. Bronchiectasis causes permanent dilation of the bronchi, leading to airflow obstruction. It is crucial to assess this history as it can provide valuable information on the patient's risk for developing COPD. A: Are you claustrophobic? - This question is not directly related to the assessment for COPD through pulmonary spirometry. B: Have you taken any bronchodilators today? - While important for assessing current medication use, it is not as crucial as determining the history of streptococcal throat infections. D: Do you use antihistamines for upper airway congestion? - Antihistamine use may not be directly linked to the risk factors for COPD development.
Question 3 of 5
A nurse is caring for a patient with a history of diabetes who is experiencing hypoglycemia. What should the nurse do first?
Correct Answer: A
Rationale: The correct answer is A: Administer glucose. The first step in managing hypoglycemia is to increase the patient's blood sugar level. Administering glucose helps to rapidly raise the blood sugar levels, which is crucial in treating hypoglycemia in a patient with diabetes. Administering insulin therapy (choice B) or insulin (choice C) would further lower the blood sugar levels, worsening the hypoglycemic state. Administering oxygen (choice D) is not indicated for hypoglycemia and would not address the underlying issue of low blood sugar levels. Administering glucose is the priority to quickly correct the hypoglycemia and prevent potential complications.
Question 4 of 5
A nurse is caring for a patient with a history of diabetes who is experiencing hypoglycemia. What is the priority intervention?
Correct Answer: B
Rationale: The correct answer is B: Administer insulin. During hypoglycemia, the priority is to raise blood sugar levels quickly to prevent further complications. Insulin administration would further lower blood sugar levels. Administering oral glucose (choice C) is the priority intervention as it rapidly increases blood sugar levels. Administering a beta-blocker (choice D) is not appropriate for hypoglycemia and can worsen the condition.
Question 5 of 5
A nurse is caring for a patient with diabetes who is experiencing hypoglycemia. What is the priority action?
Correct Answer: D
Rationale: The correct answer is D: Administer a sedative. During hypoglycemia, the brain is deprived of glucose, leading to confusion and potential loss of consciousness. Administering a sedative can help calm the patient and prevent injury from agitation. Administering glucose (A) or insulin (B) would worsen the hypoglycemia. Administering an inhaler (C) is not relevant to treating hypoglycemia.
