Renin plays a role in blood pressure regulation by
- A. activating the renin-angiotensin-aldosterone cascade.
- B. suppressing angiotensin production.
- C. decreasing sodium reabsorption.
- D. inhibiting aldosterone release.
Correct Answer: A
Rationale: The correct answer is A because renin activates the renin-angiotensin-aldosterone cascade, which ultimately leads to vasoconstriction, increased blood pressure, and aldosterone release to increase sodium and water reabsorption. Renin does not suppress angiotensin production (B), decrease sodium reabsorption (C), or inhibit aldosterone release (D), as these actions would counteract its role in blood pressure regulation.

A patient who has experienced blunt abdominal trauma during a motor vehicle collision is complaining of increasing abdominal pain. The nurse will plan to teach the patient about the purpose of:
- A. Peritoneal lavage.
- B. Abdominal ultrasonography.
- C. Nasogastric (NG) tube placement.
- D. Magnetic resonance imaging (MRI).
Correct Answer: B
Rationale: The correct answer is B: Abdominal ultrasonography. This is because ultrasonography is a non-invasive imaging technique that can quickly evaluate for internal injuries such as organ damage or bleeding in patients with blunt abdominal trauma. It is a rapid and effective diagnostic tool to assess the extent of injury and guide further management.
Peritoneal lavage (A) is an invasive procedure used in trauma settings to detect intra-abdominal bleeding but is not typically used for teaching purposes. Nasogastric tube placement (C) is used for decompression and drainage in certain conditions but is not relevant for assessing abdominal trauma. Magnetic resonance imaging (MRI) (D) is not typically used as the initial imaging modality for acute trauma due to time constraints and its limited availability in emergency settings.
A Muslim woman is admitted to the ICU after suffering severe burns over most of her body. Which of the following would be the most appropriate measure for the nurse, a woman, to take in respect for the cultural practices of this patient?
- A. Insist that only a female doctor be assigned to this patient.
- B. Ensure that no pork products are included in the patients diet.
- C. Ensure that direct eye contact is not made with the patients husband.
- D. Ask the patients husband what religious and cultural preferences should be considered in the patients care.
Correct Answer: D
Rationale: The correct answer is D because it demonstrates respect for the patient's autonomy and individual preferences. By asking the patient's husband about religious and cultural preferences, the nurse acknowledges the importance of involving the family in decision-making and shows sensitivity to the patient's beliefs. This approach promotes cultural competence and patient-centered care.
Choice A is incorrect because insisting on a female doctor may not align with the patient's preferences and may limit the available medical staff. Choice B is also incorrect as dietary restrictions are not necessarily the most pressing issue in this scenario. Choice C is incorrect as it assumes a cultural practice without verifying the patient's specific preferences and may not be necessary or appropriate in this context.
Which statement regarding ethical concepts is true?
- A. A living will is the same as a healthcare proxy.
- B. A signed donor card ensures that organ donation will o ccur in the event of brain death.
- C. A surrogate is a competent adult designated by a perso n to make healthcare decisions in the event the person is incapacitated.
- D. A persistent vegetative state is the same as brain deatha ibnir bm.cooms/tt esstt ates.
Correct Answer: C
Rationale: Rationale: Choice C is correct because a surrogate is indeed a competent adult designated to make healthcare decisions for an incapacitated person. This individual is typically chosen by the person themselves through a legal document like a healthcare proxy. This ensures that someone trusted can make important decisions when the person is unable to do so. Choices A, B, and D are incorrect because a living will and healthcare proxy serve different purposes, a signed donor card does not guarantee organ donation in the event of brain death (medical criteria are also required), and a persistent vegetative state is different from brain death (brain death implies irreversible cessation of brain function while a vegetative state involves some level of brain function).
As part of the Synergy Model, the nurse has identified a patient characteristic of resiliency. What patient behavior demonstrates resiliency?
- A. Dysfunctional grieving behaviors after receiving bad news
- B. Developing a list of questions for the physician
- C. Denial of any possible negative outcomes for a procedure
- D. Assigning blame to others for undesired outcomes of illness
Correct Answer: B
Rationale: The correct answer is B because developing a list of questions for the physician shows active engagement in their healthcare, seeking information, and taking control of their situation, which are characteristics of resiliency. This behavior indicates the patient's willingness to understand and cope with their health condition. Choices A, C, and D are incorrect as they demonstrate maladaptive coping mechanisms such as dysfunctional grieving, denial, and blame assignment, which are not indicative of resiliency. Resiliency involves adaptability, problem-solving, and seeking support, which are better exemplified by choice B.
Which of the following factors predispose the critically ill patient to pain and anxiety? (Select all that apply.)
- A. Inability to communicate
- B. Invasive procedures
- C. Monitoring devices
- D. Preexisting conditions
Correct Answer: A
Rationale: The correct answer is A: Inability to communicate. Critically ill patients often experience pain and anxiety due to their inability to effectively communicate their needs and discomfort. This can lead to unaddressed pain and increased anxiety levels. Choices B, C, and D are incorrect because while invasive procedures, monitoring devices, and preexisting conditions can contribute to pain and anxiety in critically ill patients, they are not factors that directly predispose patients to these issues. It is the lack of communication that significantly hinders the ability to address and manage pain and anxiety effectively in these patients.
