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 is being mechanically ventilated in the synchronized intermittent mandatory ventilation mode at a rate of 4 breaths/min. Spontaneous re spirations are 12 breaths/min. The patient receives a dose of morphine sulfate, and now respi rations decrease to 4 breaths/min. What adjustments may need to be made to the patient’s ve ntilator settings?
- A. Add positive end-expiratory pressure (PEEP).
- B. Add pressure support.
- C. Change to assist/control ventilation at a rate of 4 breathabsi/rmb.cionm. /test
- D. Increase the synchronized intermittent mandatory ventilation respiratory rate.
Correct Answer: C
Rationale: The correct answer is C: Change to assist/control ventilation at a rate of 4 breaths/min. When the patient's spontaneous respirations decrease to match the ventilator rate, it indicates that the patient is not actively participating in breathing. Changing to assist/control ventilation allows the patient to trigger breaths when they desire, ensuring a more synchronized and comfortable breathing pattern.
A: Adding PEEP may help improve oxygenation but is not directly related to the issue of decreased spontaneous respirations.
B: Adding pressure support provides additional support during inspiration but does not address the underlying issue of decreased spontaneous respirations.
D: Increasing the SIMV respiratory rate would not address the patient's decreased spontaneous respirations and could potentially lead to overventilation.
A patient is declared brain dead and a do not resuscitate (DNR) order is put in place. The nurse caring for the patient does not agree with this manne r of care but does not express any concerns to the charge nurse. The nurse’s feeling that the p atient is being killed will likely create what response for this nurse?
- A. A sense of abandonment
- B. Increased family stress
- C. Moral distress
- D. A sense of negligence
Correct Answer: C
Rationale: The correct answer is C: Moral distress. In this scenario, the nurse is experiencing conflicting moral values between the decision made for the patient and their own beliefs. This internal conflict leads to moral distress, a common response when healthcare professionals feel unable to act in accordance with their ethical beliefs. This can lead to emotional turmoil, frustration, and moral residue.
A: A sense of abandonment is incorrect because the nurse is still caring for the patient, so there is no physical abandonment.
B: Increased family stress is incorrect as the nurse's internal conflict does not directly impact family stress.
D: A sense of negligence is incorrect as negligence implies failure to provide proper care, which is not the case here.
In the critically ill patient, an incomplete assessment and/or management of pain or anxiety may be hampered by which of the following? (Select all that apply.)
- A. Administration of neuromuscular blocking agents
- B. Delirium
- C. Effective nurse communication and assessment skills
- D. Nonverbal patients
Correct Answer: A
Rationale: Step-by-step rationale:
1. Administration of neuromuscular blocking agents can hinder pain or anxiety assessment as it paralyzes the patient, preventing them from communicating discomfort.
2. Delirium may affect the patient's ability to express pain or anxiety, but it does not directly impede assessment and management.
3. Effective nurse communication and assessment skills facilitate, rather than hamper, pain or anxiety assessment.
4. Nonverbal patients can still communicate pain or anxiety through nonverbal cues, so they do not necessarily hinder assessment.
How should the nurse interprets these blood gas values? 2 3
- A. Compensated metabolic alkalosis
- B. Normal values
- C. Uncompensated respiratory acidosis
- D. Uncompensated respiratory alkalosis
Correct Answer: C
Rationale: The correct interpretation is uncompensated respiratory acidosis (Choice C) based on the values. Step 1: Evaluate pH - pH is <7.35, indicating acidosis. Step 2: Determine PaCO2 - PaCO2 is >45 mmHg, indicating respiratory cause. Step 3: Check HCO3- - HCO3- is within normal range, indicating uncompensated state. Choices A, B, and D are incorrect because they do not align with the given blood gas values.
A male client is angry and is leaving the hospital against medical advice (AMA). The client demands to take his chart with him and states the chart is 'his' and he doesn’t want any more contact with the hospital. How should the nurse respond?
- A. This hospital does not need to keep it if you are leaving and not returning here.
- B. Because you are leaving against medical advice, you may not have your chart.
- C. The information in your chart is confidential and cannot leave this facility legally.
- D. The chart is the property of the hospital but I will see that a copy is made for you.
Correct Answer: D
Rationale: The correct answer is D because the client's medical chart is the property of the hospital, but the client has the right to a copy of the information. By offering to make a copy of the chart for the client, the nurse respects the client's autonomy while also ensuring that the hospital maintains the original medical record. This response balances the client's rights with legal and ethical considerations.
Choice A is incorrect because the hospital is legally obligated to maintain the client's medical record even if the client leaves against medical advice. Choice B is incorrect as it denies the client access to their medical information, which goes against the principle of patient autonomy. Choice C is also incorrect as it does not address the client's request for a copy of their chart.
