A person with a blood pH of 7.21 is considered to have which of the following?
Alkalosis
Normal blood pH
Acidosis
Hyperkalemia
The Correct Answer is C
Choice A: Alkalosis
Alkalosis occurs when the blood pH is higher than the normal range, specifically above 7.45. This condition indicates that the blood is too alkaline. Causes of alkalosis can include hyperventilation, loss of stomach acid through vomiting, or an overuse of diuretics. Since a blood pH of 7.21 is below the normal range, it does not indicate alkalosis.
Choice B: Normal Blood pH
The normal pH range for blood is between 7.35 and 7.45. This range is crucial for the body’s metabolic processes and enzyme functions. A blood pH of 7.21 is below this range, indicating an abnormal condition.
Choice C: Acidosis
Acidosis is the correct answer. It occurs when the blood pH drops below 7.35, indicating that the blood is too acidic. A pH of 7.21 is significantly below the normal range, confirming acidosis. This condition can result from various factors, including respiratory issues that lead to an accumulation of carbon dioxide or metabolic problems that increase acid production or decrease bicarbonate levels.
Choice D: Hyperkalemia
Hyperkalemia refers to an elevated level of potassium in the blood, not a change in blood pH. While hyperkalemia can be associated with acidosis, it is not defined by the pH level itself. Therefore, a blood pH of 7.21 does not directly indicate hyperkalemia.

Correct Answer is A
Explanation
Choice A: Infuse the KCl at a maximum rate of 10 mEq/hr
This is the correct answer. The recommended infusion rate for potassium chloride is generally not to exceed 10 mEq per hour to avoid complications such as hyperkalemia and cardiac arrhythmias. This rate ensures that the potassium is administered safely and effectively, allowing for proper monitoring and adjustment if necessary.
Choice B: Discontinue cardiac monitoring during the infusion
This choice is incorrect. Cardiac monitoring is essential during the infusion of potassium chloride, especially in patients with severe hypokalemia, due to the risk of arrhythmias and other cardiac complications. Continuous monitoring allows for the early detection of any adverse effects and timely intervention.
Choice C: Administer the KCl as a rapid IV bolus
Administering potassium chloride as a rapid IV bolus is dangerous and contraindicated. Rapid infusion can lead to severe hyperkalemia, which can cause fatal cardiac arrhythmias. Potassium chloride should always be administered slowly and diluted in an appropriate volume of fluid.
Choice D: Refuse to give the KCl through a peripheral venous line
While central lines are preferred for higher concentrations of potassium chloride due to the risk of irritation and phlebitis, peripheral lines can be used for lower concentrations and slower infusion rates. Refusing to administer potassium chloride through a peripheral line is not necessary if the infusion is properly managed and monitored.

Correct Answer is ["B","C","E","F","H"]
Explanation
Choice A: Agency policy
While agency policy provides guidelines for reassessment intervals, it is not the primary factor in determining the specific time frame for reassessing a patient’s pain level. Policies serve as a general framework, but individual patient needs and clinical judgment should guide the reassessment timing.
Choice B: Type of intervention
This is a correct answer. The type of pain management intervention used significantly influences the reassessment time frame. For example, after administering intravenous pain medication, reassessment should occur sooner compared to oral medications due to the faster onset of action. Different interventions have varying durations of effectiveness, necessitating tailored reassessment intervals.
Choice C: Pain severity
This is another correct answer. The severity of the patient’s pain is a crucial factor in determining reassessment timing. Patients experiencing severe pain may require more frequent reassessments to ensure that pain management strategies are effective and to make timely adjustments if needed.
Choice D: If family members are present in the patient’s room
The presence of family members in the patient’s room is not a primary factor in determining the reassessment time frame. While family members can provide valuable support and information, the focus should remain on the patient’s clinical needs and the effectiveness of pain management interventions.
Choice E: The patient’s psychosocial condition
This is a correct answer. The patient’s psychosocial condition, including their emotional and mental state, can impact their perception of pain and response to pain management. Patients with anxiety, depression, or other psychosocial issues may require more frequent reassessments to address both physical and emotional aspects of pain.
Choice F: Risks for adverse effects
This is also a correct answer. The potential for adverse effects from pain management interventions necessitates careful monitoring and timely reassessment. For instance, opioids carry risks of respiratory depression and sedation, requiring close observation and frequent reassessment to ensure patient safety.
Choice G: Workload of the nurse
While the nurse’s workload can influence the practical aspects of care delivery, it should not dictate the reassessment time frame. Patient needs and clinical priorities should guide reassessment intervals, with workload management being a secondary consideration.
Choice H: The patient’s physical condition
This is the final correct answer. The patient’s overall physical condition, including comorbidities and current health status, affects their response to pain management and the need for reassessment. Patients with complex medical conditions may require more frequent monitoring to ensure effective pain control and to promptly address any complications.
