Correct Answer: B

Rationale: A pulse deficit is a crucial finding in clients with dysrhythmias as it indicates ineffective cardiac contractions. A pulse deficit occurs when the apical heart rate is faster than the radial pulse rate, suggesting that some heartbeats are not generating a pulse. This can be a sign of serious heart conditions like atrial fibrillation or heart failure. The other options, such as an increased heart rate (choice A), elevated blood pressure (choice C), and bounding pulse (choice D), do not specifically indicate ineffective cardiac contractions and are not directly associated with dysrhythmias.

Correct Answer: B

Rationale: The correct answer is B: Orange slices. For a client on a mechanical soft diet, foods that are difficult to chew and swallow should be avoided. Orange slices fall into this category due to their texture and potential choking hazard. Steamed carrots, mashed potatoes, and baked chicken are typically suitable for a mechanical soft diet as they can be easily mashed or cut into small, manageable pieces for consumption.

Correct Answer: D

Rationale: The correct answer is D: Lowered immune function. Older adults often experience a decline in immune function as they age, making them more vulnerable to infections. This weakened immune system can result in increased susceptibility to various pathogens. Choice A, 'Improved nutritional status,' is incorrect because good nutrition can actually help support the immune system. Choice B, 'Increased mobility,' is not directly related to an increased risk of infections. Choice C, 'Chronic conditions,' while they can contribute to a weakened immune system, do not directly address the primary risk factor for infections in older adults.

Correct Answer: B

Rationale: The nurse's priority action when finding a client experiencing a seizure is to place the client on their side. This action helps maintain an open airway and prevents aspiration, which is crucial during a seizure. Applying oxygen may be necessary after ensuring a patent airway, while administering an anticonvulsant is not within the nurse's scope of practice during an acute seizure. Notifying the provider can be done after ensuring the client's immediate safety.

Correct Answer: B

Rationale: The correct answer is B: Flushed skin. Flushed skin is a common finding in clients with COPD who are experiencing dyspnea. Increased breath sounds (choice A) are not typically associated with COPD; they may indicate conditions like pneumonia. Nasal flaring (choice C) is more commonly seen in respiratory distress in pediatric patients. Decreased respiratory rate (choice D) is not a typical finding in COPD and could indicate respiratory depression.
