Nursing Elites

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

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

Correct answer: A

Rationale: The combination of high TSH and low free T4 levels is consistent with hypothyroidism, which matches the patient's symptoms of fatigue, weight gain, and constipation. In hypothyroidism, the thyroid gland does not produce enough thyroid hormones, leading to a decrease in metabolic rate and resulting in these clinical findings.

2. The nurse is planning care for a client with cirrhosis of the liver. Which intervention should the nurse include to reduce the risk of bleeding?

• A. Monitor for signs of infection.
• B. Limit the client's dietary protein intake.
• C. Administer vitamin K as prescribed.
• D. Encourage the client to increase fluid intake.

Correct answer: C

Rationale: Administering vitamin K as prescribed can help reduce the risk of bleeding in clients with cirrhosis by promoting clotting factor production. Cirrhosis often leads to impaired liver function, affecting the synthesis of clotting factors. Vitamin K supplementation helps in the production of these essential clotting factors, thus reducing the risk of bleeding in clients with cirrhosis. Monitoring for signs of infection (Choice A) is important for overall care but not directly related to reducing the risk of bleeding in cirrhosis. Limiting dietary protein intake (Choice B) may be necessary in some cases of cirrhosis but does not directly address the risk of bleeding. Encouraging increased fluid intake (Choice D) is beneficial for various aspects of health but does not specifically target the risk of bleeding in cirrhosis.

3. When assessing a client with a chest tube connected to suction, which observation indicates that the chest tube is functioning properly?

• A. Continuous bubbling in the water seal chamber.
• B. Intermittent bubbling in the suction control chamber.
• C. No fluctuation in the water seal chamber.
• D. Steady bubbling in the suction control chamber.

Correct answer: D

Rationale: Steady bubbling in the suction control chamber is the correct observation that indicates the chest tube is functioning properly. This steady bubbling signifies that the suction is actively maintaining the desired pressure level within the system, ensuring proper drainage and lung re-expansion. Continuous bubbling in the water seal chamber, intermittent bubbling in the suction control chamber, or no fluctuation in the water seal chamber are not indicative of optimal chest tube function and may require further assessment or intervention.

4. 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.

5. A recently widowed middle-aged female client presents to the psychiatric clinic for evaluation and tells the nurse that she has 'little reason to live.' She describes one previous suicidal gesture and admits to having a gun in her home. To maintain the client's confidentiality and to help ensure her safety, which action is best for the nurse to implement?

• A. Encourage the client to remove the gun from her possession.
• B. Notify the client's healthcare provider of the availability of the weapon.
• C. Contact a person of the client's choosing to remove the weapon from the home.
• D. Call the local police department and have the weapon removed from the home.

Correct answer: C

Rationale: In this scenario, it is crucial to maintain the client's confidentiality while ensuring her safety. Contacting a person chosen by the client to remove the weapon from her home is the best course of action. This approach respects the client's autonomy and helps reduce the risk of harm without involving external authorities unnecessarily.
