Question 1 of 5
The nurse is preparing to give a potassium supplement. Which laboratory test should be checked before the patient receives a dose of potassium?
Correct Answer: B
Rationale: Before administering a potassium supplement to a patient, it is crucial to check the patient's serum potassium level. This is because if the serum potassium level is already elevated or within the high end of the normal range, giving additional potassium could lead to hyperkalemia, which can be life-threatening. Conversely, if the serum potassium level is low (hypokalemia), then administering potassium supplementation may be necessary to correct the deficiency. Monitoring the serum potassium level helps ensure safe and effective treatment with potassium supplements. It is a critical part of assessing the patient's electrolyte balance and overall health status.
Question 2 of 5
What is true about food and drug precautions? Select all that apply.
Correct Answer: A
Rationale: A. You must limit certain types of food or concurrent administration of certain types of drugs: Some foods can interact with certain medications, either reducing their effectiveness or causing potentially harmful side effects. Therefore, it may be necessary to limit or avoid specific foods when taking certain medications.
Question 3 of 5
A client with type 2 diabetes is prescribed insulin glargine (Lantus). Which statement by the client indicates a need for further teaching?
Correct Answer: B
Rationale: Insulin glargine, a long-acting basal insulin, provides steady glucose control without a peak. Mixing it with regular insulin is incorrect'glargine's pH precipitates if combined, altering its action, indicating a teaching need. Same-time injection ensures consistency. Overnight control and no peak align with its 24-hour, flat profile. The misconception about mixing risks erratic glucose levels, critical in type 2 diabetes where stability is key. Further teaching must clarify glargine's unique formulation, preventing administration errors that could lead to hypo- or hyperglycemia, making B the statement requiring correction.
Question 4 of 5
The nurse has completed medication education with the patient who is receiving lithium (Eskalith). What is the priority patient outcome?
Correct Answer: B
Rationale: Lithium toxicity (e.g., tremors, confusion) at narrow therapeutic range (0.6-1.2) is life-threatening-knowing signs (e.g., nausea) and prevention (e.g., hydration) is priority, per safety. Work, ADLs, and mood stability follow but aren't immediate risks. Toxicity awareness saves lives, per education.
Question 5 of 5
Which of the following does not describe intravenous injection.
Correct Answer: D
Rationale: The statement "Convenient, safe, economical" does not accurately describe intravenous injection. Intravenous injection is generally considered to be less convenient compared to other routes of administration due to the need for proper training, sterile technique, and close monitoring during drug administration. While it can be effective in delivering drugs quickly and directly into the bloodstream, it is not always the safest or most economical option. Intravenous administration carries risks such as infection, phlebitis, and possible adverse reactions that need to be carefully monitored. Additionally, the cost of intravenous drug administration tends to be higher due to the need for specialized equipment and trained personnel.
