Correct Answer: B

Rationale: The correct order of actions for the nurse in this scenario is to first obtain the oxygen saturation to assess the patient's airway and oxygenation status. Next, checking the patient's pulse rate helps in evaluating circulation. Subsequently, documenting the change in the patient's status is important for maintaining an accurate record of care. Finally, notifying the health care provider is crucial to ensure timely intervention and further management. Choices A, C, and D are incorrect because assessing oxygen saturation should precede checking the pulse rate to address potential physiological causes of confusion. Additionally, documentation should follow patient assessment and notification of the healthcare provider for appropriate record-keeping and communication.

Correct Answer: B

Rationale: For a 40-year-old patient with multiple sclerosis experiencing urinary retention due to a flaccid bladder, teaching the Cred method is the appropriate action. The Cred method involves applying manual pressure over the bladder to aid in bladder emptying. Decreasing fluid intake is not the correct approach as it will not address the underlying issue of bladder emptying and may lead to dehydration and urinary tract infections. Using adult incontinence briefs only addresses the symptom of incontinence without addressing the bladder emptying problem. Assisting the patient to the commode every 2 hours does not actively address the issue of improving bladder emptying as effectively as teaching the Cred method.

Correct Answer: C

Rationale: Patients should continue to cough and deep breathe after discharge. Fatigue is expected for several weeks. The Pneumovax and influenza vaccines can be given at the same time in different arms. Explain that a follow-up chest x-ray needs to be done in 6 to 8 weeks to evaluate resolution of pneumonia.

Correct Answer: C

Rationale: In the early phase of heart failure, fine crackles are likely to be heard upon auscultation of the lungs. Fine crackles are characterized as discontinuous, high-pitched sounds of short duration heard on inspiration. Rhonchi are continuous rumbling, snoring, or rattling sounds mainly on expiration, which are often associated with airway secretions. Coarse crackles are a series of long-duration, discontinuous, low-pitched sounds during inspiration, typically indicating fluid in the alveoli. Wheezes are continuous high-pitched musical sounds on inspiration and expiration, commonly heard in conditions like asthma or chronic obstructive pulmonary disease (COPD). Therefore, the correct choice is C, as it describes the expected lung sounds in a patient with early heart failure.

Correct Answer: B

Rationale: The correct answer is that the patient is allergic to shellfish. This is crucial because the contrast media used in CT scans is iodine-based, and individuals with iodine allergies, such as those allergic to shellfish, are at risk of adverse reactions. It is important to identify and address this allergy to prevent potential complications. The other options do not directly impact the safety or effectiveness of the CT scan with contrast media. Claustrophobia can be managed with patient support, the recent use of a bronchodilator inhaler does not typically affect the CT procedure, and not being able to remove a wedding band is not a critical concern for the scan itself.
