What are the key nursing considerations for a patient with a central venous catheter?

Correct Answer: A

Rationale: The correct answer is A: Maintain sterility during dressing changes. It is crucial to maintain sterility during dressing changes for patients with central venous catheters to prevent infections. Changing the dressing weekly (Choice B) is not frequent enough to prevent infections effectively. Monitoring blood pressure and fluid balance (Choice C) is important for overall patient care but not specific to central venous catheter management. While monitoring the catheter site for infection (Choice D) is important, the key consideration is to prevent infections through proper sterile techniques during dressing changes.

Correct Answer: B

Rationale: The priority for a client with dehydration is to monitor electrolyte levels to prevent imbalances. Dehydration can lead to electrolyte disturbances, which can have serious consequences. Administering antiemetics (Choice A) may help with nausea but does not address the root cause of dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels is crucial in managing dehydration. Administering intravenous fluids (Choice D) is important in severe cases of dehydration, but monitoring electrolytes should come first to assess the extent of the imbalance and guide fluid replacement therapy effectively.

Correct Answer: B

Rationale: In conscious clients with hypoglycemia, the most appropriate action is to provide a rapidly absorbed carbohydrate source like fruit juice to raise blood glucose levels quickly. Administering glucagon intramuscularly (IM) is usually reserved for unconscious clients or those who are unable to take oral glucose. Providing peanut butter or water would not rapidly address the hypoglycemic state as fruit juice would.

Correct Answer: B

Rationale: The correct answer is to suction the tracheostomy first. When a client with a tracheostomy is experiencing increased secretions and labored breathing, suctioning the tracheostomy is the priority intervention to clear the airway and improve breathing. Administering a bronchodilator (Choice A) may help with breathing but should come after ensuring the airway is clear. Encouraging the client to cough (Choice C) may not be effective in clearing secretions from the tracheostomy. Notifying the provider (Choice D) can be done after ensuring immediate airway clearance.

Correct Answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

Correct Answer: A

Rationale: Corrected Rationale: Untreated fluid overload can lead to complications such as pulmonary edema and congestive heart failure. Pulmonary edema occurs when excess fluid accumulates in the lungs, leading to difficulty breathing and potentially life-threatening respiratory distress. Congestive heart failure can result from the heart's inability to pump effectively due to the excess fluid volume, leading to symptoms such as fatigue, shortness of breath, and fluid retention. Choices B, C, and D are incorrect because hypertension, liver failure, pulmonary embolism, and dehydration are not the primary complications directly associated with untreated fluid overload.

Correct Answer: A

Rationale: The correct answer is a low-protein diet for a patient with chronic kidney disease. In chronic kidney disease, the kidneys may have difficulty filtering waste products from protein metabolism, leading to a buildup of toxins in the body. Therefore, reducing protein intake can help lessen the workload on the kidneys. Choices B, C, and D are incorrect. A high-protein diet would increase the workload on the kidneys, while a low-sodium diet is beneficial for conditions like hypertension or heart failure but not specifically targeted for chronic kidney disease. A high-sodium diet can worsen fluid retention and hypertension in patients with kidney disease.

Correct Answer: C

Rationale: Choice C is the correct answer. During a colonoscopy, clients are typically sedated, so they do not feel any pain during the procedure. Choices A, B, and D are incorrect. Clients are usually required to stop eating and drinking at least 24 hours before a colonoscopy, and there are specific dietary restrictions that need to be followed before the procedure to ensure a successful examination.

Correct Answer: A

Rationale: The correct procedure for taking a telephone order from a provider is to state the patient's name, drug, dose, route, frequency, and then read back the order to ensure accuracy. This process helps in preventing errors and ensures that all relevant information is correctly documented. Choice B is incorrect because having a witness listen to the order is not a standard practice and may not guarantee accuracy. Choice C is incorrect as verifying the order within 12 hours may lead to delays in patient care. Choice D is incorrect because waiting for the provider to verify the order during the next in-person visit could result in a significant delay in administering necessary medication.
