Question 1 of 5
A client is prescribed with carbamazepine (Tegretol) for the treatment of bipolar disorder. Which of the following laboratory results indicates that the client is experiencing a side effect of this medication?
Correct Answer: A
Rationale: Carbamazepine can cause leukopenia, including neutropenia, as a side effect. A neutrophil count of 1,200/mm3 is below the normal range and indicates a potential adverse effect. Platelet count, uric acid, and SGPT levels are within normal ranges and do not indicate side effects.
Therefore, the neutrophil count is the concerning result.
Question 2 of 5
Which statement is accurate concerning the use of aspirin (ASA) to treat pain?
Correct Answer: B
Rationale: Aspirin's use for pain involves anti-inflammatory and analgesic properties, but it risks GI irritation. Enteric-coated capsules minimize this by dissolving in the intestine, not the stomach, reducing bleeding risk—an accurate statement. High doses are true for anticoagulation, not pain relief, where lower doses suffice. Herbs like garlic and ginger increase bleeding risk, not inflammation relief, making it dangerous advice. Low doses (choice D, 325 mg) primarily prevent clotting, not significantly reduce inflammation, which requires higher doses.
Choice B correctly reflects a practical measure to enhance aspirin's safety profile for pain management.
Question 3 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 4 of 5
The following drugs can induce malignant hyperthermia:
Correct Answer: B
Rationale: Succinylcholine is a trigger for malignant hyperthermia in susceptible individuals due to its effects on calcium release in muscle cells.
Question 5 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.
