Correct Answer: C

Rationale: The correct answer is C because using an electric razor instead of a safety razor demonstrates understanding of the risk of injury associated with thrombocytopenia. This action shows practical application of the teaching to prevent bleeding. Choice A only indicates awareness but not necessarily action. Choice B shows knowledge but not necessarily application. Choice D is related to general healthcare knowledge but not directly linked to bleeding prevention in thrombocytopenia.

Correct Answer: C

Rationale: The correct answer is C: Interdependent intervention. This type of nursing intervention involves collaboration with other healthcare professionals to provide holistic care. In this scenario, the nurse is following a protocol set by the health care agency, which likely involves input and guidance from various team members. The nurse's actions require coordination and communication with others to ensure the best outcome for the client. Choice A (Independent intervention) would involve actions that the nurse can perform autonomously without requiring direction from others. Choice B (Dependent intervention) would require an order or prescription from a healthcare provider for the nurse to carry out. Choice D (Collaborative intervention) involves working together with other healthcare professionals on a specific aspect of care, but in this case, the nurse is primarily following a set protocol without necessarily actively collaborating with others during the task.

Correct Answer: A

Rationale: The correct answer is A: Maintenance of a clear airway. In cases of coma or unconsciousness, ensuring a clear airway is crucial to prevent respiratory complications and maintain oxygenation. This involves positioning the patient correctly, suctioning if necessary, and monitoring breathing. Choice B, good nursing care, is too broad and does not address the immediate priority of airway management. Choice C, retention of a catheter, is irrelevant to managing a coma or unconsciousness. Therefore, the correct therapeutic measure in this scenario is to focus on maintaining a clear airway to support respiratory function.

Correct Answer: D

Rationale: The correct answer is D because a respiratory rate of 8 breaths/min indicates respiratory depression, a serious adverse effect of morphine. Morphine is a central nervous system depressant that can suppress the respiratory drive, leading to hypoventilation and potentially respiratory failure. This is a life-threatening complication that requires immediate intervention. A: Voiding of 350mL of concentrated urine is not typically associated with morphine use. B: An irregular heart rate of 82 beats/min is within a normal range and not a common adverse effect of morphine. C: Pupils constricted and equal is a common side effect of morphine due to its action on the central nervous system, not necessarily indicating an adverse effect.

Correct Answer: A

Rationale: The correct answer is A because asthma is characterized by inflammation and bronchoconstriction of the airways, leading to difficulty breathing. This explanation accurately describes the pathophysiology of asthma. Explanation for other choices: B: Fluid in the lungs is more indicative of conditions like pneumonia or pulmonary edema, not asthma. C: Asthma involves airway constriction and inflammation, not stretching and non-functionality. D: Asthma is not caused by infection but rather triggered by factors like allergens or irritants.
