Nursing Elites

1. A 45-year-old woman presents with fatigue, weight gain, and constipation. Laboratory tests reveal low TSH and high free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: B

Rationale: The presentation of low TSH and high free T4 levels is characteristic of hyperthyroidism, which is consistent with the symptoms of fatigue, weight gain, and constipation described in the case. In hyperthyroidism, the thyroid gland produces an excess of thyroid hormone leading to a hypermetabolic state, which can manifest with these symptoms.

2. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

3. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

4. A client with a diagnosis of schizophrenia is being treated with risperidone (Risperdal). Which finding should the nurse report to the healthcare provider immediately?

• A. Weight gain.
• B. Dry mouth.
• C. Muscle rigidity.
• D. Drowsiness.

Correct answer: C

Rationale: Muscle rigidity is a crucial finding to report immediately as it can indicate neuroleptic malignant syndrome (NMS), a rare but potentially life-threatening reaction to antipsychotic medications. NMS is characterized by muscle rigidity, high fever, autonomic dysfunction, and altered mental status. Prompt recognition and intervention are essential to prevent serious complications or death.

5. The client with newly diagnosed hypertension is being taught about lifestyle modifications. Which recommendation should be made?

• A. Increase your intake of saturated fats.
• B. Limit your alcohol intake to two drinks per day.
• C. Engage in at least 150 minutes of moderate exercise per week.
• D. Use table salt liberally to season your food.

Correct answer: C

Rationale: Engaging in at least 150 minutes of moderate exercise per week is a key lifestyle modification recommended for individuals with hypertension. Regular exercise helps manage blood pressure, improve cardiovascular health, and overall well-being. It is important for the client to adopt a healthy lifestyle to control hypertension and reduce the risk of complications.
