A 65-year-old patient admitted to the progressive care unit with a diagnosis of community-acquired pneumonia, has a history of chronic obstructive pulmonary disease and diabetes. A set of arterial blood gases obtained on admissiaobnir bw.coitmh/oteustt supplemental oxygen shows pH 7.35; PaCO 55 mm Hg; bicarbonate 30 mEq/L ; PaO 65 mm Hg. These blood 2 2 gases reflect what condition?
- A. Hypoxemia and compensated metabolic alkalosis.
- B. Hypoxemia and compensated respiratory acidosis.
- C. Normal oxygenation and partly compensated metaboli c alkalosis.
- D. Normal oxygenation and uncompensated respiratory acidosis.
Correct Answer: B
Rationale: The correct answer is B: Hypoxemia and compensated respiratory acidosis. The patient's pH is within normal range (7.35), indicating compensation. The elevated PaCO2 (55 mm Hg) indicates respiratory acidosis due to inadequate ventilation, likely from COPD. The low PaO2 (65 mm Hg) indicates hypoxemia, common in pneumonia. The normal bicarbonate level (30 mEq/L) suggests metabolic compensation for respiratory acidosis. Choice A is incorrect as there is no metabolic alkalosis present. Choice C is incorrect as the patient has hypoxemia. Choice D is incorrect as the patient is showing compensated respiratory acidosis, not uncompensated.

A 15-year-old boy is in the ICU and preparing for an appendectomy. He is clearly anxious and fidgets with his IV constantly. He complains that he doesnt want to be there and he is sick of everyone telling him what to do. What would be the best way for the nurse to address this patients anxiety?
- A. Use physical restraints to keep him from pulling out his IV.
- B. Offer him the remote to the television.
- C. Lower the head of his bed so that he can rest more easily.
- D. Explain to the patient in detail what the appendectomy will consist of.
Correct Answer: B
Rationale: The correct answer is B: Offer him the remote to the television. This is the best way to address the patient's anxiety because it provides a distraction and a sense of control, which can help alleviate anxiety. By offering the patient the remote to the television, the nurse is giving him a choice and a way to focus his attention away from his anxiety. This can help him feel more comfortable and empowered in the situation.
Choice A is incorrect because using physical restraints can increase the patient's anxiety and sense of helplessness. Choice C, lowering the head of his bed, may provide physical comfort but does not directly address his anxiety. Choice D, explaining the procedure in detail, may further increase his anxiety as it focuses on the surgery rather than addressing his current emotional state.
What factors associated with the critical care unit can pred ispose the client to increased pain and anxiety? (Select all that apply.)
- A. Presence of an endotracheal tub
- B. Frequent vital sign assessment
- C. Monitor alarms
- D. Room temperature
Correct Answer: A
Rationale: The presence of an endotracheal tube can predispose the client to increased pain and anxiety due to discomfort, difficulty breathing, and potential for aspiration. The tube insertion process itself can be painful and traumatic. Frequent vital sign assessment, monitor alarms, and room temperature are not directly associated with increased pain and anxiety from the endotracheal tube.
When caring for a patient with a pulmonary artery (PA) pressure catheter, the nurse observes that the PA waveform indicates that the catheter is in the wedged position. Which action should the nurse take next?
- A. Zero balance the transducer.
- B. Activate the fast flush system.
- C. Notify the health care provider.
- D. Deflate and reinflate the PA balloon.
Correct Answer: C
Rationale: The correct answer is C: Notify the health care provider. When the PA waveform indicates the catheter is in the wedged position, it means the catheter tip is in the pulmonary artery, potentially causing complications. The nurse should notify the healthcare provider immediately to assess and reposition the catheter to prevent further issues. Zero balancing the transducer (A) or activating the fast flush system (B) are not appropriate actions for this situation. Deflating and reinflating the PA balloon (D) could exacerbate the issue and should only be done under the guidance of the healthcare provider.
Which of the following statements describes the core conc ept of the synergy model of practice?
- A. All nurses must be certified in order to have the synerg y model implemented.
- B. Family members must be included in daily interdisciplaibnirabr.cyo mro/teusnt ds.
- C. Nurses and physicians must work collaboratively and synergistically to influence care.
- D. Unique needs of patients and their families influence nursing competencies.
Correct Answer: D
Rationale: Rationale:
D is correct because the synergy model focuses on individualized care based on patients' unique needs. This model emphasizes tailoring nursing competencies to address these needs, promoting holistic care. A is incorrect as certification is not a requirement. B involves family inclusion but does not capture the core concept. C mentions collaboration but does not specifically address individualized care.
Which statement about family assessment is false?
- A. Assessment of structure (who comprises the family) is the last step in assessment.
- B. Interaction among family members is assessed.
- C. It is important to assess communication among family members to understand roles.
- D. Ongoing assessment is important, because family funcatbioirbn.cinomg/ tmesat y change during the course of illness.
Correct Answer: A
Rationale: The correct answer is A because assessing the structure of the family (who comprises the family) is not the last step in family assessment. The rationale is that understanding the family structure is essential at the beginning of the assessment process to identify key relationships and support systems. Assessing interaction among family members helps to understand dynamics and relationships within the family. Assessing communication is crucial to identify roles and patterns of interaction. Ongoing assessment is necessary as family dynamics can evolve throughout the illness. Therefore, A is false as family structure assessment is an important initial step, not the last step.
