A nurse is collecting data from a client who has hypokalemia as a result of nausea, vomiting, and diarrhea.
Which of the following findings should the nurse expect?
Extreme thirst.
Weak, irregular pulse.
Hyperactive bowel sounds.
Hyperactive reflexes.
The Correct Answer is B
Choice A rationale:
Extreme thirst is not a typical finding in a client with hypokalemia. Hypokalemia is an electrolyte imbalance that can lead to symptoms like weakness and irregular heartbeats, but extreme thirst is not a direct result of low potassium levels.
Choice B rationale:
"Weak, irregular pulse" is the correct response. Hypokalemia can lead to cardiac arrhythmias, which may manifest as a weak, irregular pulse. Potassium plays a crucial role in maintaining the electrical activity of the heart, and low levels can disrupt normal heart rhythms.
Choice C rationale:
Hyperactive bowel sounds are not typically associated with hypokalemia. Instead, you might expect diminished or absent bowel sounds in severe cases due to muscle weakness.
Choice D rationale:
Hyperactive reflexes are not typically associated with hypokalemia. Instead, hypokalemia can lead to muscle weakness and potentially even paralysis in severe cases.

Correct Answer is A
Explanation
Choice A rationale:
The nurse should instruct the client to discontinue the dose of acetylsalicylic acid (aspirin) 2 weeks before surgery. Aspirin is an antiplatelet medication that can increase the risk of bleeding during and after surgery. Discontinuing it before surgery helps reduce the risk of excessive bleeding during the procedure. The recommended time frame for discontinuation may vary based on the patient's surgical procedure and the surgeon's preferences. However, 2 weeks is a common guideline to ensure that the antiplatelet effects of aspirin have diminished.
Choice B rationale:
Decreasing the dose by half 2 weeks before surgery may not be sufficient to minimize the risk of bleeding associated with aspirin. It is generally recommended to discontinue the medication completely to ensure that the antiplatelet effect has worn off.
Choice C rationale:
Taking the originally prescribed dose of aspirin the week of surgery is not advisable because it can increase the risk of bleeding during the surgical procedure. It is important to discontinue aspirin well before the surgery.
Choice D rationale:
Doubling the dose of aspirin the week of surgery is contraindicated as it can significantly increase the risk of bleeding. This choice is not recommended in the context of preoperative management.
Correct Answer is A
Explanation
Choice A rationale:
Hypovolemic shock is characterized by a decrease in blood volume, leading to low blood pressure and compensatory mechanisms such as a high pulse rate. When the body experiences a significant loss of blood or fluid, it attempts to maintain perfusion to vital organs by increasing the heart rate to ensure an adequate blood supply. Low blood pressure and a high pulse rate are classic signs of hypovolemic shock.
Choice B rationale:
A low BP and low pulse rate are not indicative of hypovolemic shock. Hypovolemic shock is associated with a rapid and weak pulse rate as the body tries to compensate for decreased blood volume. A low pulse rate could suggest other conditions, such as bradycardia, rather than hypovolemic shock.
Choice C rationale:
High BP and high pulse rate are not typical findings in hypovolemic shock. Hypovolemic shock is characterized by low blood pressure and a high pulse rate as the body attempts to compensate for the reduced blood volume. High blood pressure is more commonly associated with conditions like hypertension, not hypovolemic shock.
Choice D rationale:
High BP and low pulse rate are not consistent with the characteristics of hypovolemic shock. As mentioned earlier, hypovolemic shock is marked by low blood pressure and a high pulse rate due to the body's efforts to maintain adequate perfusion. High blood pressure and a low pulse rate may suggest other medical conditions unrelated to hypovolemic shock.
