Nursing Elites

1. 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.

2. A patient with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). What is the priority nursing action?

• A. Administer regular insulin intravenously.
• B. Give oral hypoglycemic agents.
• C. Administer sodium bicarbonate.
• D. Provide a high-calorie diet.

Correct answer: A

Rationale: The priority nursing action for a patient with type 1 diabetes mellitus admitted with diabetic ketoacidosis (DKA) is to administer regular insulin intravenously. Insulin helps to lower blood glucose levels and correct acidosis, which are critical in managing DKA. Administering oral hypoglycemic agents is not appropriate in the acute setting of DKA as they may not work quickly enough compared to intravenous insulin. While sodium bicarbonate may be used to correct acidosis, insulin administration is the priority to address both hyperglycemia and acidosis simultaneously. Providing a high-calorie diet is not suitable initially in DKA management; the main focus is on stabilizing the patient's condition through insulin therapy and fluid/electrolyte correction.

3. What is/are the possible cause(s) of acute pancreatitis in this patient?

• A. HIV
• B. Cytomegalovirus
• C. Dideoxyinosine (ddI)
• D. Pentamidine

Correct answer: B

Rationale: This patient presents with symptoms and lab findings consistent with acute pancreatitis. Cytomegalovirus is a common viral infection associated with pancreatitis. In patients with AIDS, the pancreas can be affected by various infections (e.g., cryptococcus, Mycobacterium tuberculosis, candida, Toxoplasma gondii) and medications (such as ddI, pentamidine, trimethoprim/sulfamethoxazole, metronidazole) can also lead to acute pancreatitis. While HIV infection predisposes individuals to various opportunistic infections, in this case, the most likely cause of the acute pancreatitis is cytomegalovirus infection.

4. A client with left-sided heart failure is experiencing dyspnea and orthopnea. Which position should the nurse place the client in to relieve these symptoms?

• A. High Fowler's position.
• B. Supine position.
• C. Trendelenburg position.
• D. Sims' position.

Correct answer: A

Rationale: Placing the client in High Fowler's position is beneficial for individuals with left-sided heart failure experiencing dyspnea and orthopnea. This position helps to reduce venous return, decrease preload, and enhance respiratory function, thereby relieving the symptoms mentioned. Choice B, the supine position, is not recommended as it may exacerbate dyspnea and orthopnea by increasing preload. Choice C, the Trendelenburg position, is incorrect as it involves the feet being positioned higher than the head, which is not suitable for heart failure patients. Choice D, the Sims' position, is a lateral position used for rectal examination and is not indicated for relieving dyspnea and orthopnea in heart failure.

5. The nurse is caring for a client with hyperthyroidism. Which intervention should the nurse implement to manage the client's condition?

• A. Provide a high-calorie diet.
• B. Encourage frequent rest periods.
• C. Restrict fluid intake.
• D. Administer a stool softener.

Correct answer: B

Rationale: Encouraging frequent rest periods is essential in managing hyperthyroidism as it helps address the fatigue and hypermetabolic state commonly associated with this condition. Rest is crucial to support the body's recovery and reduce the stress on the thyroid gland. While nutrition is important in managing hyperthyroidism, providing a high-calorie diet is not the priority intervention. Restricting fluid intake is not typically necessary unless there are specific indications such as heart failure. Administering a stool softener is not directly related to managing hyperthyroidism.
