Critical Care Nursing Questions and Answers PDF

Correct Answer: A

Rationale: The correct answer is A: Obtain the permission of the custodial parent for the surgery. In this scenario, the client is a minor (16 years old), which means they are not legally able to provide informed consent for medical procedures. The custodial parent holds legal responsibility for the minor's healthcare decisions. Thus, obtaining the permission of the custodial parent is crucial to ensure valid informed consent. Choice B is incorrect because the non-custodial parent's consent may not be legally required if the custodial parent is available to provide consent. Choice C is incorrect because obtaining consent should precede any administration of medications. Choice D is incorrect as the stepfather's consent may not hold legal weight unless designated as a legal guardian.

Correct Answer: B

Rationale: The correct answer is B because informed consent requires the patient to have knowledge and competence to make a decision. This involves understanding the risks, benefits, and alternatives of the proposed treatment. Choice A is incorrect as it pertains to a physical ability unrelated to decision-making. Choice C is incorrect as consent must be verbal or written, not just nodding. Choice D is incorrect as consent can be obtained in various ways, not specifically through reading and writing in English.

Correct Answer: A

Rationale: The correct answer is A: Apply external cooling device. Therapeutic hypothermia is a treatment used to protect the brain after cardiac arrest by lowering the body temperature. The nurse should use external cooling devices, such as cooling blankets or ice packs, to achieve and maintain the desired temperature. This method allows for precise temperature control and monitoring. Checking mental status every 15 minutes (choice B) is not the priority as maintaining the temperature is crucial. Avoiding sedative medications (choice C) may be necessary to accurately assess the patient's neurological status. Rewarming if the temperature is <91�F (32.8�C) (choice D) is incorrect as the goal is to maintain hypothermia for a specific duration before gradual rewarming.

Correct Answer: A

Rationale: The correct answer is A: 46.8; meets criteria for ARDS. The PaO /FiO ratio is calculated by dividing the arterial oxygen partial pressure (PaO) by the fraction of inspired oxygen (FiO). In this case, PaO is 78 mm Hg and FiO is 0.6 (60%). Therefore, the calculation would be 78/0.6 = 130. This value is less than 300, which is indicative of ARDS according to the Berlin criteria. Choices B and C are incorrect as they do not align with the criteria for ARDS. Choice D is incorrect because the data provided is sufficient to compute the ratio.

Correct Answer: C

Rationale: The correct answer is C: Anxiety related to lack of knowledge about normal grieving. This is because the patient is expressing uncertainty and seeking validation for their feelings, indicating a lack of understanding about the grieving process. Choice A is incorrect as hopelessness typically involves feelings of despair and loss of motivation, which are not explicitly stated by the patient. Choice B is incorrect as complicated grieving involves specific unresolved issues related to the loss, which the patient did not mention. Choice D is incorrect as chronic sorrow is typically associated with ongoing feelings of sadness and longing, which are not explicitly expressed by the patient.
