The nurse is caring for a client who requires a mechanical ventilator for breathing. The high-pressure alarm goes off on the ventilator. What is the first action the nurse should perform?

A. Disconnect the client from the ventilator and use a manual resuscitation bag

B. Perform a quick assessment of the client's condition

C. Call the respiratory therapist for help

D. Press the alarm reset button on the ventilator

Correct Answer: B
Rationale: When the high-pressure alarm on a ventilator goes off, the nurse's initial action should be to perform a quick assessment of the client's condition. This assessment helps in promptly identifying the cause of the alarm, such as mucus plugging, kinking of the tubing, or other issues. By assessing the client first, the nurse can determine the appropriate intervention needed to address the alarm. Choices A and D are incorrect because disconnecting the client from the ventilator or pressing the alarm reset button should not be the initial actions without assessing the client's condition. While calling the respiratory therapist for help could be beneficial, assessing the client's condition should be the nurse's priority to address the immediate concern.

A nurse is reinforcing teaching with a client who has constipation about a high-fiber diet. Which of the following foods should be included as sources of fiber? Select one that doesn't apply.

• A. Kidney beans
• B. Strawberries
• C. Peanut butter
• D. Whole wheat bread

Correct Answer: C
Rationale: The correct answer is C, Peanut butter. While kidney beans, strawberries, and whole wheat bread are high-fiber foods that help alleviate constipation, peanut butter is not a significant source of fiber. Peanut butter is more known for its protein and healthy fats content rather than being a good source of dietary fiber. Therefore, it should not be included as a primary recommendation for a high-fiber diet in the context of addressing constipation.

A client is diagnosed with methicillin-resistant Staphylococcus aureus pneumonia. What type of isolation is most appropriate for this client?

• A. Reverse
• B. Airborne
• C. Standard precautions
• D. Contact

Correct Answer: D
Rationale: The correct answer is 'D: Contact.' Contact precautions are necessary for clients with MRSA pneumonia to prevent the spread of the resistant bacteria. MRSA is primarily spread by direct contact, so using contact precautions, such as wearing gloves and gowns, is essential. Choice A, 'Reverse,' is not a type of isolation precaution. Choice B, 'Airborne,' is not the appropriate isolation for MRSA pneumonia, as MRSA is not transmitted through the airborne route. Choice C, 'Standard precautions,' are important for all clients, but for MRSA pneumonia specifically, contact precautions are more targeted and necessary.

A client who is to have antineoplastic chemotherapy tells the nurses of a fear of being sick all the time and wishes to try acupuncture. Which of these beliefs stated by the client would be incorrect about acupuncture?

• A. Some needles go as deep as 3 inches, depending on where they're placed in the body and what the treatment is for. The needles are usually left in for 15 to 30 minutes.
• B. In traditional Chinese medicine, imbalances in the basic energetic flow of life — known as qi or chi — are thought to cause illness.
• C. The flow of life is believed to flow through major pathways in your body rather than nerve clusters.
• D. By inserting extremely fine needles into some of the over 400 acupuncture points in various combinations, it is believed that energy flow will rebalance to allow the body's natural healing mechanisms to take over.

Correct Answer: C
Rationale: The belief stated in option C is incorrect about acupuncture. Acupuncture is based on the concept of qi flowing through major pathways in the body, known as meridians, rather than nerve clusters. This traditional Chinese medicine practice aims to balance the flow of qi to promote health and healing. Options A, B, and D are consistent with the principles of acupuncture and are not incorrect beliefs. Option A describes the depth and duration of needle placement, option B explains the role of imbalances in qi flow causing illness, and option D outlines how acupuncture helps rebalance energy flow for the body's natural healing mechanisms.

A nurse is collecting data from a client who has hypocalcemia. Which of the following findings should the nurse expect?

• A. Decreased deep-tendon reflexes
• B. Skeletal muscle weakness
• C. Hypoactive bowel sounds
• D. Tingling of the lips

Correct Answer: D
Rationale: The correct answer is D, tingling of the lips (perioral tingling). This is a common symptom of hypocalcemia due to increased neuromuscular excitability. Choice A, decreased deep-tendon reflexes, is more indicative of hypercalcemia. Choice B, skeletal muscle weakness, is associated with hypokalemia. Choice C, hypoactive bowel sounds, is not a typical finding in hypocalcemia.
