The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. Total volume after reconstitution is 2.5 mL. After reconstitution, how many mL should be administered to the client? (Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).

Choice A rationale:

Addiction involves a dependence on a substance or behavior that leads to withdrawal symptoms when the substance or behavior is discontinued. The client's handwashing behavior is not related to addiction.

Choice B rationale:

Phobia refers to an irrational and intense fear of a specific object or situation. While the client's avoidance of sitting on chairs in the day area may be related to anxiety, it does not represent a specific phobia.

Choice C rationale:

Compulsion is the correct answer because the client's handwashing ritual is an example of compulsive behavior. Compulsions are repetitive behaviors or mental acts that a person feels driven to perform in response to an obsession or according to rigid rules. In this case, the client is compelled to engage in the ritual to alleviate anxiety or distress.

Choice D rationale:

Obsession refers to persistent and intrusive thoughts, urges, or images that cause distress and anxiety. While the client's handwashing ritual may be related to obsessive thoughts about cleanliness, the primary clinical behavior being exhibited is the compulsive handwashing itself.

Choice A rationale:

Reporting the 24-hour intake at the current infusion rate is not the most important finding to report to the healthcare provider in this case. It is essential to monitor intake and output, but a single report of the 24-hour intake is not as critical as other findings.

Choice B rationale:

Reporting a serum potassium level of 3.1 mEq/L (3.1 mmol/L) is the most important finding to report to the healthcare provider. The patient's potassium level is below the normal range, indicating hypokalemia. Hypokalemia can have serious cardiac and neuromuscular effects, including arrhythmias and muscle weakness. Prompt intervention, such as potassium supplementation or adjustment of IV fluids, is necessary to address this potentially life-threatening condition.

Choice C rationale:

Reporting a gastric output of 900 mL in the last 24 hours is significant and should be reported to the healthcare provider, but it is not as urgent as the low potassium level. Gastric output should be monitored to assess for signs of improvement or worsening, but hypokalemia takes precedence due to its immediate health risks.

Choice D rationale:

Reporting an increased blood urea nitrogen (BUN) is important for the overall assessment of the patient's renal function but is not the most critical finding in this scenario. The low potassium level is a more immediate concern and requires immediate attention.
