Which statement is an important nursing implication in the management of a client who is taking trimethoprim/sulfamethoxazole for a urinary tract infection?
A. Extended periods outside in sunshine are important for vitamin D for this client
Trimethoprim/sulfamethoxazole does not require extended sun exposure. In fact, it causes photosensitivity, increasing sunburn risk, so patients should avoid prolonged sunlight. Vitamin D synthesis is unrelated to this antibiotic’s mechanism or side effects, making this statement inaccurate and potentially harmful for patient safety.
B. Clients should be told to expect brown urine while taking this medication
Trimethoprim/sulfamethoxazole does not typically cause brown urine. Brown urine may indicate hematuria or other conditions, but it is not a common side effect of this drug. The medication may cause gastrointestinal upset or rash, but urine discoloration is not expected, making this statement inaccurate.
C. Follow-up with the Health Care Provider is unnecessary
Follow-up with a healthcare provider is necessary to ensure UTI resolution and monitor for side effects like rash, renal impairment, or rare hematologic effects. This statement is inaccurate, as lack of follow-up could miss treatment failure or complications, undermining effective management of the infection.
D. Client should be monitored for anemia
Trimethoprim/sulfamethoxazole can cause bone marrow suppression, leading to anemia, particularly in patients with folate deficiency or prolonged use. Monitoring complete blood counts is critical to detect hemolytic anemia or other hematologic toxicities, making this statement accurate and essential for safe patient management during treatment.

Full Explanation
Choice A reason: Trimethoprim/sulfamethoxazole does not require extended sun exposure. In fact, it causes photosensitivity, increasing sunburn risk, so patients should avoid prolonged sunlight. Vitamin D synthesis is unrelated to this antibiotic’s mechanism or side effects, making this statement inaccurate and potentially harmful for patient safety.
Choice B reason: Trimethoprim/sulfamethoxazole does not typically cause brown urine. Brown urine may indicate hematuria or other conditions, but it is not a common side effect of this drug. The medication may cause gastrointestinal upset or rash, but urine discoloration is not expected, making this statement inaccurate.
Choice C reason: Follow-up with a healthcare provider is necessary to ensure UTI resolution and monitor for side effects like rash, renal impairment, or rare hematologic effects. This statement is inaccurate, as lack of follow-up could miss treatment failure or complications, undermining effective management of the infection.

A client admitted for injuries from a motor vehicle crash has a history of bipolar disorder for which he takes lithium. What is a major concern of the nurse?
A. Lithium toxicity is likely in the client’s treatment
Lithium toxicity is a concern but not inevitable. It occurs with levels above 1.5 mEq/L, often due to dehydration or drug interactions, common in trauma settings. However, routine monitoring of levels is a more immediate nursing priority than assuming toxicity, as early detection prevents severe outcomes like seizures or renal damage.
B. Lithium is completely metabolized by the liver so liver function tests are indicated
Lithium is primarily excreted by the kidneys, not metabolized by the liver. Liver function tests are not indicated for lithium monitoring, as it does not undergo hepatic metabolism. This statement is inaccurate, as renal function tests are critical to assess lithium clearance and prevent toxicity in trauma patients.
C. Lithium requirements increase with stress so additional lithium may be required
Stress does not directly increase lithium requirements. Trauma-related dehydration or renal impairment can elevate lithium levels, risking toxicity, but this is due to reduced clearance, not increased need. This statement is inaccurate, as dosing adjustments should be based on serum levels, not stress alone.
D. Lithium has a very narrow therapeutic range so lithium levels should be obtained
Lithium has a narrow therapeutic range (0.6-1.2 mEq/L), and trauma-related factors like dehydration or medications can alter levels, risking toxicity or subtherapeutic effects. Regular serum level monitoring is critical, especially in acute settings, to ensure safety and efficacy, making this statement accurate and a priority nursing concern.

A client is scheduled for a procedure for treatment of hyperthyroidism. Prior to the procedure, the client will be given medications to reach an euthyroid state. What is the rationale for doing this?
A. Prevent possible hypothyroidism
Achieving euthyroid state before hyperthyroidism procedures, like thyroidectomy, aims to normalize thyroid hormone levels, not prevent hypothyroidism. Post-procedure hypothyroidism is a separate concern managed with hormone replacement. This statement is inaccurate, as the primary goal is to stabilize metabolism, not prevent low thyroid function.
B. Prevent thyroid storm
Medications like methimazole or propylthiouracil are used pre-procedure to achieve euthyroid state, reducing thyroid hormone levels to prevent thyroid storm—a life-threatening hypermetabolic crisis triggered by surgery or stress. This statement is accurate, as stabilizing thyroid function minimizes perioperative complications like tachycardia or hyperthermia.
C. Help medications for hyperthyroidism be more effective
Euthyroid state does not directly enhance the efficacy of anti-thyroid medications but rather prepares the patient for surgery by reducing hyperthyroid symptoms. Medications are effective independently, and this statement is inaccurate, as the rationale focuses on patient safety, not drug potentiation.
D. Minimize the risk of bleeding during the surgical procedure
While euthyroid state reduces metabolic stress, it does not primarily minimize bleeding risk. Bleeding is managed through surgical techniques and coagulation status, not thyroid hormone levels. This statement is inaccurate, as bleeding risk is not the primary concern addressed by achieving euthyroid state pre-procedure.

The nurse is assessing a client with suspected Gastroesophageal Reflux Disease (GERD). Which word or statement is an accurate characteristic of GERD?
A. Melena
Melena, dark tarry stools from digested blood, indicates upper gastrointestinal bleeding, not typically GERD. GERD involves acid reflux causing esophageal irritation, not bleeding severe enough for melena. This statement is inaccurate, as melena is more associated with ulcers or varices, not reflux disease.
B. Heartburn
Heartburn, a burning sensation in the chest, is a hallmark of GERD, caused by stomach acid refluxing into the esophagus, irritating the mucosa. It results from lower esophageal sphincter dysfunction, allowing acid backflow. This statement is accurate, as heartburn is a primary diagnostic symptom of GERD.
C. Hematemesis
Hematemesis, vomiting blood, is not a common GERD symptom but indicates severe conditions like esophageal varices or ulcers. While chronic GERD may lead to esophagitis, bleeding is rare. This statement is inaccurate, as hematemesis is not a characteristic feature of typical GERD presentations.
D. Dysphagia
Dysphagia, difficulty swallowing, can occur in severe GERD due to esophageal strictures or motility issues but is not a primary characteristic. Heartburn is more common and diagnostic. This statement is less accurate, as dysphagia is a complication, not a defining feature of GERD.
