1. A nurse reviews a female client’s laboratory results. Which result from the client’s urinalysis should the nurse recognize as abnormal?
- A. pH 5.6
- B. Ketone bodies present
- C. Specific gravity of 1.020
- D. Clear and yellow color
Correct answer: B
Rationale: The correct answer is B: Ketone bodies present. Ketone bodies in urine indicate abnormal metabolism, specifically the incomplete breakdown of fatty acids. Normally, there should be no ketones present in urine. Ketone bodies are produced when the body uses fat sources instead of glucose for cellular energy. A pH range between 4.6 and 8, a specific gravity between 1.005 and 1.030, and clear yellow color in urine are considered normal findings for a female client’s urinalysis. Therefore, options A, C, and D are within normal ranges and not indicative of abnormal results in the urinalysis.
2. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 62, PaCO2 59, and HCO3. Which statement describes the most likely cause of the simultaneous increase in both the PaO2 and the PaCO2?
- A. The hypercapnia resulted from the rapid respirations.
- B. The hypoxic drive was reduced by the oxygen therapy.
- C. The client had a pneumothorax which restricted ventilation.
- D. The client had a pulmonary embolism that reduced perfusion.
Correct answer: B
Rationale: In patients with COPD, oxygen therapy can reduce the hypoxic drive, which is the primary stimulus for breathing in these individuals. By providing supplemental oxygen, the hypoxic drive is diminished, resulting in decreased respiratory effort. As a consequence, the PaO2 may increase due to the supplemental oxygen, but this can lead to a decrease in the respiratory drive and subsequent retention of carbon dioxide, causing an increase in PaCO2 levels. Option A is incorrect because rapid respirations would typically lower PaCO2 levels. Option C is incorrect as a pneumothorax would lead to impaired gas exchange and decreased PaO2 levels without necessarily affecting PaCO2 levels. Option D is incorrect as a pulmonary embolism would typically result in ventilation-perfusion mismatch and decreased PaO2 levels without directly impacting PaCO2 levels.
3. When planning activities for a socialization group for older residents of a long-term facility, what information would be most useful for the nurse?
- A. The length of time each resident has resided at the facility.
- B. A brief description of each resident's family life.
- C. The age of each resident.
- D. The usual activity patterns of each resident.
Correct answer: D
Rationale: The most useful information for the nurse when planning activities for a socialization group for older residents of a long-term facility would be the usual activity patterns of each resident. An older person's level of activity is a determining factor in adjustment to aging, as described by the Activity Theory of Aging. By understanding the usual activity patterns of each resident, the nurse can tailor activities that cater to their interests and abilities, promoting social engagement and overall well-being. The other options, such as the length of time residing at the facility, a brief description of family life, or the age of each resident, may provide some insights but do not directly relate to planning activities that support adjustment to aging and socialization within the group.
4. A client with acute glomerulonephritis (GN) is being evaluated by a nurse. Which manifestation should the nurse recognize as a positive response to the prescribed treatment?
- A. The client has lost 11 pounds in the past 10 days.
- B. The client’s urine specific gravity is 1.048.
- C. No blood is observed in the client’s urine.
- D. The client’s blood pressure is 152/88 mm Hg.
Correct answer: A
Rationale: A weight loss of 11 pounds in the past 10 days indicates fluid loss, a positive response to treatment for acute glomerulonephritis. It signifies that the glomeruli are functioning adequately to filter excess fluid. A urine specific gravity of 1.048 is high, indicating concentrated urine, which is not a positive response in this context. Blood in the urine is not a typical finding in glomerulonephritis, so its absence is expected and does not indicate a positive response to treatment. A blood pressure of 152/88 mm Hg is elevated and may suggest kidney damage or fluid overload, which are not positive responses to treatment.
5. A client with chronic renal failure is prescribed a low-protein diet. The nurse should explain to the client that the purpose of this diet is to:
- A. Prevent fluid overload.
- B. Reduce the workload on the kidneys.
- C. Prevent dehydration.
- D. Maintain electrolyte balance.
Correct answer: B
Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.
