A client with HIV has been prescribed anti viral medications. What instructions related to administration of medications should the nurse give such a client?
- A. Comply with the timing of antiviral medication around meals
- B. Avoid exposure to harsh sunlight for about 2hrs after taking the medication
- C. Have the medications with plenty of fruit juice
- D. Have an increased dose of the medications if the symptoms worsen
Correct Answer: A
Rationale: The nurse should instruct the client to comply with the timing of antiviral medication around meals. Taking some antiviral medications with food can help reduce gastrointestinal side effects. Certain medications may be more effective when taken with food, while others may need to be taken on an empty stomach. It is essential for the client to follow the specific instructions given by their healthcare provider to ensure the optimal effectiveness of the antiviral medications.
A patient with abnormal sodium losses is receiving a house diet. To provide 1,600mg sodium daily, the nurse could supplement the patient's diet with:
- A. One beef cube and 8oz of tomato juice
- B. One beef cube and 16oz of tomato juice
- C. Four beef cubes and 8oz of tomato juice
- D. One beef cube and 12oz tomato juice
Correct Answer: D
Rationale: One beef cube typically contains about 800mg of sodium, and 8oz of tomato juice contains approximately 480mg of sodium. Therefore, to provide a total of 1,600mg of sodium daily, the nurse could supplement the patient's diet with one beef cube (800mg sodium) and 12oz of tomato juice (720mg sodium). This combination would effectively provide the required 1,600mg of sodium per day for the patient with abnormal sodium losses.
A client with serum glucose level of 618mg/dl is admitted to the facility. He's awake and oriented, has hot dry skin, and has the following vital signs: temperature of 100.6F (38.1C), heart rate of 116 beats/min, and blood pressure of 108/70mHg. Based on these assessment findings, which nursing diagnosis take highest priority?
- A. Deficient volume related to osmotic diuresis
- B. Decreased cardiac output related to elevated heart rate
- C. Imbalanced nutrition: Less than body requirements related to insulin deficiency
- D. Ineffective thermoregulation related to dehydration
Correct Answer: A
Rationale: The client's serum glucose level of 618mg/dl is indicative of severe hyperglycemia, likely due to uncontrolled diabetes mellitus. The client's presentation with hot dry skin, elevated heart rate, and low blood pressure suggests dehydration as a result of osmotic diuresis, which occurs in an attempt to excrete excess glucose. With an elevated heart rate and low blood pressure, it is essential to address the deficient volume to prevent further complications such as hypovolemic shock. Rehydration and fluid replacement are crucial interventions to help restore the client's fluid balance and prevent hemodynamic instability. Addressing the deficient volume related to osmotic diuresis should take the highest priority in this case.
The nurse knows that Parkinson's disease a progressive neurologic disorder is characterized by:
- A. Bradykinesia
- B. Tremor
- C. Muscle rigidity
- D. All of the above
Correct Answer: D
Rationale: Parkinson's disease is a progressive neurologic disorder that is characterized by a triad of symptoms known as the classic Parkinsonian triad. These symptoms include bradykinesia (slowness of movement), tremor (involuntary shaking), and muscle rigidity (stiffness of the muscles). Therefore, all of the given choices are correct in describing the characteristics of Parkinson's disease.
You are assigned to evaluate the outcome of fecal occult blood test as a screening test for patients with bowel cancer. The total number of patients who underwent the test is 2030; in those whom the disease is confirmed are 30. The results of fecal occult blood test are as follows: in 20 patients who has a confirmed bowel cancer (truly positive), and in 180 patients who don't have the disease (falsely positive); in 10 patients who truly has the disease (falsely negative), and in 1820 patients who are not affected by the disease (truly negative). All the following statements are true EXCEPT
- A. the prevalence of the disease for those population is 1.48%
- B. the sensitivity of the test is 67%
- C. the specificity of the test is 91%
- D. the positive predictive value is 20%
Correct Answer: A
Rationale: Prevalence = (Total cases / Total population) * 100 = (30 / 2030) * 100 ≈ 1.48%. This statement is correct, so it is the exception as the question asks for the incorrect statement.
