Correct Answer: D

Rationale: When a client refuses medication, the nurse should inform the client of the possible consequences of refusal. This action helps the client understand the risks associated with not taking the medication. Asking the client to discuss their feelings (choice A) is important but should follow after informing them of the consequences. Explaining the importance of the medications (choice B) might not address the immediate concern of the client. Documenting the refusal and withholding the medication (choice C) should be done after informing the client of the consequences and attempting to address their concerns.

Correct Answer: A

Rationale: The correct nursing priority for a patient experiencing an asthma exacerbation is to administer a bronchodilator. Bronchodilators help in relieving bronchoconstriction and improving breathing. While encouraging deep breathing, providing oxygen therapy, and monitoring oxygen saturation are essential aspects of managing asthma exacerbation, the priority is to administer a bronchodilator to address the acute bronchoconstriction.

Correct Answer: C

Rationale: The correct answer is C: 'Poor lighting.' External factors such as lighting can significantly impact the learning environment, making it difficult for participants to engage effectively. Poor lighting can strain the eyes, cause discomfort, and lead to decreased concentration. Choices A, B, and D are internal factors or issues that are not directly related to the learning environment. High workload, limited knowledge on the subject, and limited space in the learning area may affect learning differently but do not impede learning through external factors like poor lighting does.

Correct Answer: D

Rationale: The correct answer is D: Consumption of contaminated food. Hepatitis A is primarily transmitted through the ingestion of contaminated food or water. Airborne droplets and sexual contact are not common modes of transmission for hepatitis A. While contact with contaminated surfaces can play a role in the spread of some infections, hepatitis A is not typically transmitted through this route.

Correct Answer: B

Rationale: The correct answer is B: 'As soon as the client awakens in the morning.' Sputum specimens should be collected early in the morning to obtain a concentrated sample. This timing ensures that the specimen is less diluted, providing a more accurate analysis. Choices A, C, and D are incorrect as they do not align with the optimal timing for collecting a sputum specimen, which is in the morning.
