The nurse is caring for a client complaining of intense headaches with increasing pain for the past one month. An MRI is ordered. In reviewing the client's information, which piece of information is of concern?

Correct Answer: B

Rationale: The correct answer is 'Has a cardiac pacemaker.' If a client with a cardiac pacemaker undergoes an MRI, the magnetic field can interfere with the pacemaker's function, leading to serious complications or even death. It is crucial to ensure that the pacemaker is compatible with MRI imaging or to consider alternative imaging modalities. The other choices, such as 'Allergy to shellfish,' 'A diabetic,' and 'No IV access,' are not direct contraindications for an MRI scan and do not pose the same level of risk as having a cardiac pacemaker.

Correct Answer: B

Rationale: The most important information for the nurse to record after discontinuing a peripherally inserted central line (PICC) is the length and intactness of the central line catheter. This is crucial for assessing any potential complications or safety issues post-removal. Choices A, C, and D are not as critical as ensuring the condition of the central line catheter. While noting the client's tolerance of the procedure is relevant for their care assessment, evaluating the central line's integrity takes precedence in this scenario.

Correct Answer: C

Rationale: The correct answer is 'Lateral.' When a client is very drowsy or sedated, placing them in the lateral position is important to maintain an open airway and allow for drainage of secretions. This position helps prevent airway obstruction and aspiration. Choice A, 'Supine,' is lying flat on the back and may not be ideal for a drowsy client due to the risk of airway compromise. Choice B, 'Fowlers,' is a semi-sitting position that is beneficial for clients with respiratory distress, but it may not be the best choice for a very drowsy individual. Choice D, 'High Fowlers,' is a more upright sitting position, which again may not be suitable for a drowsy client as it does not facilitate airway patency as effectively as the lateral position.

Correct Answer: C

Rationale: The correct assessment finding consistent with a flail chest is paradoxical chest wall movement. This occurs when a segment of the chest wall moves in the opposite direction to the rest of the chest during respiration. Biot's respirations (Choice A) are a pattern of breathing characterized by groups of quick, shallow inspirations followed by regular or irregular periods of apnea. Sucking sounds during respirations (Choice B) may indicate air entering or leaving the chest cavity through a wound. Hypotension and bradycardia (Choice D) may be present due to other factors such as shock, but they are not specific to a flail chest.

Correct Answer: A

Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.
