With pulmonary edema, there is usually an alteration in:
- A. Afterload
- B. Preload
- C. Contractility
- D. All of the above
Correct Answer: D
Rationale: Pulmonary edema causes an increase in pressure in the pulmonary circulation, leading to an alteration in afterload due to increased resistance. It also causes fluid accumulation in the pulmonary vessels, affecting preload. Additionally, the heart may compensate by increasing contractility. Therefore, all of the above choices are altered in pulmonary edema. The incorrect choices are A, B, and C individually as they only represent one aspect of the alterations seen in pulmonary edema, while the correct answer D encompasses all three factors affected in this condition.

A client was brought to the emergency room with complains of difficulty of breathing. What can lead the nurse to suspect that the client is experiencing acute respiratory distress syndrome (ARDS)?
- A. paO2 of 95, pCO2 of 43, x-ray showing enlarged heart, bradycardia
- B. Thick green sputum production, paO2 of 74, pH of 7.41
- C. restlessness, suprasternal retractions, paO2 of 62
- D. wheezes, slow, deep respirations, pCO2 of 52, pH of 7.35
Correct Answer: C
Rationale: Step-by-step rationale for choice C being correct:
1. Restlessness: Indicates increased work of breathing and hypoxia.
2. Suprasternal retractions: Sign of respiratory distress.
3. paO2 of 62: Indicates severe hypoxemia, common in ARDS.
Summary:
A: Enlarged heart on x-ray does not directly indicate ARDS.
B: Thick green sputum suggests infection, not specific to ARDS.
D: Wheezes and slow respirations are not typical of ARDS, and pCO2 is normal in ARDS.
A goal for a patient with diabetes is to demonstrate effective coping skills. Which patient behavior will indicate to the nurse achievement of this outcome?
- A. States feels better after talking with family and friends
- B. Consumes high-carbohydrate foods when stressed
- C. Dislikes the support group meetings
- D. Spends most of the day in bed
Correct Answer: A
Rationale: The correct answer is A because stating feeling better after talking with family and friends demonstrates the use of healthy coping skills. This behavior indicates the patient is seeking and utilizing social support, which is crucial for managing stress and emotions effectively in diabetes management. Choices B, C, and D are incorrect because consuming high-carbohydrate foods when stressed can lead to poor blood sugar control, disliking support group meetings indicates avoidance of beneficial support resources, and spending most of the day in bed can contribute to physical and emotional deterioration, rather than effective coping.
The nurse is assigned to a client with polymyositis. Which expected outcome in the plan of care relates to a potential problem associated with polymyositis?
- A. “Client will lose 2lb per week on a calorie-restricted diet.”
- B. “Client will exhibit no signs or symptoms of aspiration.”
- C. “Client will exhibit bowel and bladder continence.”
- D. “Client will exhibit alertness and orientation to person, place, and time.” DISTURBANCES IN IMMUNOLOGIC FUNCTIONING
Correct Answer: E
Rationale: I'm sorry, but it seems like the correct answer (E) is missing from the question. Could you please provide the correct answer so that I can provide you with a detailed explanation of why it is correct and summarize why the other choices are incorrect?
A patient was diagnosed with hiatal hernia. She frequently has regurgitation and a sour taste on his mouth especially after eating large meals. Which action by the client shows understanding of her treatment regimen?
- A. elevate her legs when she is sleeping
- B. drink more fluids with her meals
- C. increase the roughage in her diet
- D. avoid caffeine, alcohol, and chocolate
Correct Answer: D
Rationale: The correct answer is D: avoid caffeine, alcohol, and chocolate. This helps to reduce acid reflux symptoms associated with hiatal hernia. Caffeine, alcohol, and chocolate can relax the lower esophageal sphincter, leading to increased reflux. Elevating legs (choice A) does not address the underlying issue. Drinking more fluids (choice B) can exacerbate symptoms by increasing stomach volume. Increasing roughage (choice C) may worsen symptoms due to increased gastric distension. By avoiding triggers like caffeine, alcohol, and chocolate, the client can effectively manage her symptoms.
Management of hypercalcemia includes all of the following actions except administration of:
- A. Fluid to dilute the calcium le⁺vels
- B. The diuretic furosemide (Lasix), without saline, to increase calcium excretion through kidneys
- C. Inorganic phosphate salts
- D. Intravenous phosphate therapy
Correct Answer: B
Rationale: The correct answer is B because administration of the diuretic furosemide without saline is not recommended for managing hypercalcemia. Furosemide can lead to volume depletion and potentially exacerbate hypercalcemia by concentrating calcium levels in the blood.
A: Fluid administration helps dilute calcium levels by increasing urine output.
C: Inorganic phosphate salts can bind with calcium in the gut, reducing absorption.
D: Intravenous phosphate therapy can help lower calcium levels by promoting calcium-phosphate complex formation.
In summary, B is incorrect as it may worsen hypercalcemia, while A, C, and D are valid strategies for managing hypercalcemia.
