Question 1 of 9

Which intervention is most effective in preventing the spread of infection in a healthcare setting?

Correct Answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

Question 2 of 9

The nurse is caring for a client who is NPO (nothing by mouth) due to a small bowel obstruction. Which nursing intervention is most important?

Correct Answer: B

Rationale: Providing frequent oral care is crucial when a client is NPO to ensure comfort and prevent drying of the oral mucosa. In this situation, the priority is maintaining oral hygiene to prevent complications such as oral mucosa breakdown. Monitoring bowel sounds may be important in assessing bowel activity, but it is not the priority when the client is NPO due to a small bowel obstruction. Encouraging ambulation can be beneficial for other conditions, but in this case, oral care takes precedence. Measuring abdominal girth is more relevant for assessing abdominal distention, which is not the priority when the client is NPO. Therefore, the most important nursing intervention is to provide frequent oral care.

Question 3 of 9

A client with a history of stroke presents with dysphagia. What is the most important nursing intervention to prevent aspiration?

Correct Answer: B

Rationale: The correct answer is B: Position the client in a high-Fowler's position during meals. Placing the client in a high-Fowler's position (sitting upright at a 90-degree angle) helps reduce the risk of aspiration by ensuring that the airway is protected during swallowing. This position facilitates easier swallowing and decreases the likelihood of food or liquids entering the respiratory tract. Encouraging the client to drink water between meals (choice A) does not directly address the risk of aspiration during meals. Providing thickened liquids (choice C) may be necessary for some patients with dysphagia but is not the most important intervention to prevent aspiration. Allowing the client to eat quickly (choice D) without proper positioning and precautions can increase the risk of aspiration.

Question 4 of 9

During the assessment of a client who has suffered a stroke, what finding would indicate a complication?

Correct Answer: A

Rationale: Difficulty swallowing (dysphagia) can indicate complications such as aspiration risk, which is common after a stroke due to impaired swallowing reflexes. It poses a serious threat to the client's respiratory system. Options B, C, and D are less likely to indicate immediate complications post-stroke. A slight headache is a common complaint and may not necessarily indicate a complication. High blood pressure is a known risk factor for strokes but may not be an immediate post-stroke complication unless it is severely elevated. Muscle weakness on one side is a common sign of stroke but may not directly indicate a new complication.

Question 5 of 9

The client is being taught about a low-sodium diet. Which food should the client avoid?

Correct Answer: B

Rationale: The correct answer is B: Canned vegetables. Canned vegetables are often high in sodium due to the preservation process, so they should be avoided on a low-sodium diet. Fresh fruits (choice A), fresh chicken (choice C), and unsalted nuts (choice D) are all low-sodium options and can be included in a low-sodium diet. It is important to choose fresh or frozen vegetables over canned ones to reduce sodium intake. Fresh chicken and unsalted nuts are also good protein sources that are naturally low in sodium, making them suitable for a low-sodium diet. Therefore, clients following a low-sodium diet should prioritize fresh, whole foods over processed or canned options.

Question 6 of 9

The nurse is preparing to administer a subcutaneous injection of heparin. What is the correct angle of insertion?

Correct Answer: C

Rationale: The correct angle of insertion for a subcutaneous injection, such as heparin, is 45 degrees. This angle is appropriate as it helps to ensure proper delivery of the medication into the subcutaneous tissue. Option A (15 degrees) is too shallow for a subcutaneous injection and may result in the medication being deposited into the muscle. Option B (30 degrees) is also too shallow for subcutaneous injections. Option D (90 degrees) is used for intramuscular injections, not subcutaneous injections.

Question 7 of 9

When teaching a diabetic client about foot care, what information is most important?

Correct Answer: A

Rationale: Inspecting feet daily is crucial for diabetic clients as it can help prevent complications like infections and ulcers. This practice allows for early detection of any foot issues, enabling timely intervention. While wearing cotton socks (choice B) is beneficial as they absorb moisture and reduce the risk of fungal infections, it is not as critical as daily foot inspection. Using lukewarm water to wash feet (choice C) is important to prevent burns or skin damage in diabetic clients with decreased sensation, but it is not as crucial as daily foot inspection. Cutting nails straight across (choice D) is essential to prevent ingrown nails, but it is not the most important information when educating diabetic clients about foot care.

Question 8 of 9

The nurse is in charge of a Nursing unit in a long-term care facility. Which task is best for the nurse to assign to an unlicensed assistive personnel (UAP) who is helping with the care of several clients?

Correct Answer: B

Rationale: The correct answer is B because cleaning the perineal area is a task within the scope of practice for unlicensed assistive personnel (UAPs) and is crucial for preventing infections. Choice A involves a more complex task that requires a healthcare provider's assessment. Choice C involves a sterile procedure that should be performed by licensed staff. Choice D involves specific care for a client with a catheter that exceeds the UAP's scope of practice.

Question 9 of 9

What is the most important action to prevent complications while caring for a client receiving enteral nutrition via a nasogastric tube?

Correct Answer: A

Rationale: Checking tube placement before each feeding is crucial to prevent aspiration, a serious complication of enteral nutrition. Ensuring the tube is correctly positioned in the stomach helps avoid the risk of the feeding going into the lungs, which can lead to aspiration pneumonia. Flushing the tube with water (Choice B) is important for maintaining tube patency but is not the most critical action to prevent complications. Elevating the head of the bed (Choice C) helps reduce the risk of aspiration but is not as crucial as verifying tube placement. Administering the feeding at room temperature (Choice D) is more related to patient comfort and does not directly address the prevention of complications associated with enteral nutrition via a nasogastric tube.
