Question 1 of 9
Your patient has alcoholism, and you may suspect during your assessment that his serum magnesium is low. What will the nurse potentially expect to assess related to hypomagnesemia?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 9
Your patient has the following arterial blood gas results: pH 7.26, PaCO2 28, HCO3 11 mEq/L. How would the nurse interpret the results?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 9
A patient is taking spironolactone (Aldactone) to control her hypertension. Her serum potassium level is 6 mEq/L. For this patient, the nurse's priority would be to assess her:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 9
A patient who is hospitalized with a possible electrolyte imbalance is disoriented and weak, has an irregular pulse, and takes hydrochlorothiazide. He most likely suffers from:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 9
A nurse admitting a patient with a history of emphysema reviews her past lab reports and notes that the patient's PaCO2 has been 56 to 64 mmHg. The nurse will be cautious administering oxygen because:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 6 of 9
When selecting a site on the hand or arm for insertion of an IV catheter, the nurse should:
Correct Answer: B
Rationale: When selecting a site for insertion of an IV catheter, the nurse should choose a distal site, not a proximal site. Selection of a distal site leaves the upper veins available for subsequent cannulations. Instruct the patient to hold his arm in a dependent position to increase blood flow. Never leave a tourniquet in place longer than 2 minutes.
Question 7 of 9
The nurse preparing a site for the insertion of an IV catheter should treat excess hair at the site by:
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 8 of 9
A patient's lab results show a slight decrease in potassium. The physician has declined to treat with drug therapy but has suggested increasing the potassium through diet. Which of the following would be a good source of potassium?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 9 of 9
A 65-year-old male patient was admitted to a medical-surgical unit 72 hours ago with pyloric stenosis; a nasogastric tube was inserted upon admission and has been on low intermittent suction since then. The nurse taking care of the patient notices that his potassium is very low and becomes concerned that the patient may be at risk for:
Correct Answer: C
Rationale: Probably the most common cause of metabolic alkalosis is vomiting or gastric suction with loss of hydrogen and chloride ions. The disorder also occurs in pyloric stenosis in which only gastric fluid is lost. Vomiting, gastric suction, and pyloric stenosis all remove potassium and can cause hypokalemia.
