1. In hanging a parenteral IV fluid that is to be infused by gravity, rather than with an infusion pump, the nurse notes that the IV tubing is available in different drop factors. Which tubing is a microdrop set?
- A. 15 drops per milliliter
- B. 60 drops per milliliter
- C. 20 drops per milliliter
- D. 10 drops per milliliter
Correct answer: B
Rationale: A microdrop set delivers 60 drops per milliliter of IV fluid. This allows for a more precise control of the infusion rate. The correct choice is B because it provides the desired microdrop rate. Choices A, C, and D are incorrect. A delivers 15 drops per milliliter, which is a macrodrop set. C delivers 20 drops per milliliter, also a macrodrop set. D delivers 10 drops per milliliter, another macrodrop set. Therefore, the correct choice for a microdrop set is B.
2. A patient has been diagnosed with diabetes mellitus. Which of the following is not a clinical sign of diabetes mellitus?
- A. Polyphagia
- B. Polyuria
- C. Metabolic acidosis
- D. Lower extremity edema
Correct answer: D
Rationale: Polyphagia, polyuria, and metabolic acidosis are common clinical signs of diabetes mellitus. Polyphagia refers to excessive hunger, polyuria is excessive urination, and metabolic acidosis can occur due to poorly controlled diabetes. Lower extremity edema, on the other hand, is not a typical clinical sign of diabetes mellitus. Edema in the lower extremities is more commonly associated with conditions like heart failure or kidney disease rather than diabetes mellitus.
3. In conducting a community health fair for a group of middle-aged citizens, which statement should the nurse emphasize in reducing the risk of coronary heart disease?
- A. Participate in at least 30 minutes of moderate physical activity 3 to 5 days per week.
- B. Engage in an aerobic exercise class every day.
- C. Limit your alcohol intake to a moderate level.
- D. The best way to lose weight is to follow a balanced diet.
Correct answer: B
Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.
4. Following a thyroidectomy, a client is complaining of shortness of breath (SOB) and neck pressure. Which nursing action is the best response?
- A. Stay with the client, remove the dressing, and elevate the head of bed.
- B. Call a code, open the trach set, and position the client supine.
- C. Have the client say "EEE"? to check for laryngeal integrity.
- D. Immediately go to the nurse's station and call the physician
Correct answer: A
Rationale: Correct! The client is displaying signs of respiratory distress after a thyroidectomy. By staying with the client, removing the dressing around the neck, and elevating the head of the bed, the nurse can assess the airway and breathing status more effectively. This immediate action can help alleviate any potential airway obstruction. Choice B is incorrect because calling a code and opening the trach set without initial assessment and basic interventions may delay necessary actions. Choice C is incorrect as having the client say "EEE"? is not as immediate or effective in addressing the respiratory distress. Choice D is incorrect as leaving the client alone and calling the physician without providing immediate assistance can be detrimental in a situation of potential airway compromise.
5. A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?
- A. COPD clients are stimulated to breathe by hypoxia.
- B. COPD clients depend on a low carbon dioxide level.
- C. COPD clients tend to retain hydrogen ions if they are given high doses of oxygen.
- D. COPD clients thrive on a high oxygen level.
Correct answer: A
Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.
