While measuring a client's vital signs, the nurse notices an irregularity in the heart rate. Which nursing action is appropriate?

Correct Answer: A

Rationale: The appropriate nursing action when an irregularity in the heart rate is observed is to count the apical pulse rate for a full minute and describe the rhythm in the chart. This approach helps in obtaining an accurate assessment of the irregularities present. Measuring the blood pressure (Choice B) is important but not the immediate priority when an irregular heart rate is noted. Performing an ECG (Choice C) may be necessary but is a more advanced intervention that should follow the initial assessment. Rechecking the heart rate after 5 minutes (Choice D) may delay potential interventions for addressing the irregularity, making it less appropriate than the immediate assessment and documentation of the pulse rhythm.

Correct Answer: D

Rationale: The correct answer is D because in middle adulthood, individuals often shift their focus towards concerns related to the next generations. They reflect on their roles in guiding and supporting the younger generations. Choice A is incorrect as evaluating behavior after a social interaction is more relevant to self-awareness, which is not a specific developmental task for middle adulthood. Choice B, learning to trust others, is more commonly associated with early adulthood tasks related to forming intimate relationships. Choice C, wishing to find meaningful friendships, is more aligned with tasks associated with young adulthood and social connections.

Correct Answer: B

Rationale: The correct answer is to use electrical tape to secure extension cords next to baseboards on the floor. This practice helps prevent tripping and electrical hazards by keeping cords out of the way. Option A is incorrect as unplugging electronics should be done by holding the plug, not the cord itself. Option C is incorrect because when using a fire extinguisher, it should be aimed at the base of the flames, not at the top. Option D is not directly related to home safety teaching and may not be necessary for all clients, as it suggests an unnecessary change that may not improve safety.

Correct Answer: D

Rationale: The correct answer is D. Delegating the task of ambulating a client who had a stroke 2 days ago to an AP is appropriate. This task falls within the scope of practice for an AP and can help promote mobility and prevent complications. Choices A, B, and C involve more complex nursing assessments or procedures that require a higher level of training and expertise. Taking orthostatic blood pressure measurements, monitoring a peripheral IV insertion site, and performing a central line dressing change should be tasks performed by licensed nurses to ensure proper assessment and management of the client's condition.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. Pheochromocytoma is characterized by the overproduction of catecholamines, leading to symptoms such as hypertension. Bradycardia (Choice B) is not typical in pheochromocytoma as increased catecholamines usually lead to tachycardia. Hypoglycemia (Choice C) and weight gain (Choice D) are not commonly associated symptoms of pheochromocytoma.

Correct Answer: C

Rationale: In a 2-year-old child with diarrhea and a possible ear infection, rectal temperature measurement is the most accurate reflection of core body temperature. This method provides the most reliable reading, especially in young children, as it closely reflects the core body temperature. Oral temperature may not be accurate due to the child's recent diarrhea, which can affect oral readings. Axillary temperature may not be as accurate as rectal temperature in this case. Temporal temperature measurement, although non-invasive, may not provide the most accurate core body temperature reading, especially in a child with a potential ear infection.

Correct Answer: C

Rationale: The correct answer is C because insulin needles should be disposed of after a single use to prevent infection. Reusing the same needle for three days can lead to infection and is not a safe practice. Choices A, B, and D demonstrate good understanding of insulin administration and diabetes management, so they do not indicate a need for further teaching.

Correct Answer: A

Rationale: Choice A is correct because applying oxygen through a tube in the nose provides comfort and aligns with the client's wishes for palliative care without resuscitation. This intervention can help alleviate breathing difficulties and maintain comfort without initiating full resuscitation efforts, respecting the client's decision. Choice B is incorrect as it goes against the client's expressed wish to decline resuscitation in her living will. Choice C is not the most appropriate response as it does not directly address the client's immediate concern of difficulty breathing and lacks specificity. Choice D, although focusing on comfort measures, is less specific than the correct choice A in addressing the client's immediate need for assistance with breathing.

Correct Answer: D

Rationale: The correct answer is to assist the client to an upright position. When a client is having difficulty breathing, promoting optimal oxygenation is essential. Elevating the head of the bed improves ventilation and lung expansion by reducing pressure on the diaphragm. This position allows the lungs to expand fully, enhancing oxygen exchange. Suctioning the airway may be necessary if there are secretions causing obstruction, but it is not the first intervention in this scenario. Administering a bronchodilator is appropriate for bronchoconstriction but does not address the immediate need for better ventilation. Increasing humidity can be beneficial in certain respiratory conditions, but it is not the initial priority when a client is struggling to breathe.
