A nurse teaches a client who is prescribed nicotine replacement therapy. Which statement should the nurse include in this client's teaching?

Correct Answer: C

Rationale: The correct answer is C. Smoking while taking nicotine replacement therapy can increase the risk of a stroke due to the combination of nicotine intake from smoking and the therapy. This is important for the client to understand to avoid potential serious health complications. A: Making a list of reasons why smoking is bad is not directly related to the client's use of nicotine replacement therapy. B: Rising slowly when getting out of bed is a general safety measure and not specific to nicotine replacement therapy. D: Stopping nicotine replacement therapy suddenly does not increase the risk for a heart attack; rather, it may lead to withdrawal symptoms.

Correct Answer: C

Rationale: The correct answer is C: Giving pure Oxygen Carbon dioxide mixture. When hemoglobin binds with carbon monoxide (CO) instead of oxygen, it forms carboxyhemoglobin (COHb), which decreases the oxygen-carrying capacity of blood. Administering pure oxygen helps to displace CO from hemoglobin, but giving pure oxygen alone may not be sufficient in severe cases. By providing a mixture of pure oxygen and carbon dioxide, the increased carbon dioxide levels can help stimulate breathing and aid in the elimination of CO from the body more rapidly. This approach can help restore oxygen levels in the blood more effectively compared to just giving pure oxygen. Dialysis and blood transfusion are not immediate remedies for carbon monoxide poisoning and are not as directly targeted at addressing the underlying issue of COHb formation.

Correct Answer: D

Rationale: Step 1: Pulse oximetry is a non-invasive method of measuring SaO2 by using a sensor attached to a patient's fingertip, earlobe, or toe. Step 2: It provides immediate and continuous monitoring of oxygen saturation levels in the blood, making it an efficient and reliable method. Step 3: Pulse oximetry is widely used in clinical settings due to its accuracy and convenience. Step 4: In contrast, the other options are not direct methods for assessing SaO2. Incentive spirometry helps improve lung function, ABG measures blood pH and gases, and peak flow measures airflow in the lungs.

Correct Answer: D

Rationale: The correct answer is D: Chest wall invasion. An MRI would be ordered to assess for any potential invasion of the chest wall by the suspected bronchogenic carcinoma. MRI provides detailed imaging of soft tissues and can help determine the extent of tumor invasion beyond the lungs. Explanation: A: Alveolar dysfunction - Alveolar dysfunction is typically assessed using pulmonary function tests or imaging techniques like CT scans, not MRI. B: Forced vital capacity - Forced vital capacity is a measure of lung function and is not typically assessed using MRI. C: Tidal volume - Tidal volume is a measure of the volume of air moved in and out of the lungs during normal breathing and is not assessed using MRI in this context.

Correct Answer: D

Rationale: During hyperpnea, which is increased rate and depth of breathing, both inspiration and expiration require muscular contractions. Inspiration involves the diaphragm contracting and external intercostal muscles expanding the rib cage, while expiration involves the internal intercostal muscles contracting to decrease the thoracic cavity volume. This increased muscular effort is necessary to meet the increased oxygen demand of the body during hyperpnea. Options A and C are incorrect as they incorrectly describe either inspiration or expiration as passive. Option B is incorrect as it inaccurately states that expiration is passive, which is not the case during hyperpnea.
