A client who is unstable and requires frequent vital signs has an electronic blood pressure machine automatically measuring his blood pressure every 15 min. However, the machine is reading the client's blood pressure at more frequent intervals, and the readings are not similar. The nurse checks the machine settings and observes the additional readings, but the problem continues. Which of the following is the appropriate nursing action?

Correct Answer: B

Rationale: The correct action in this scenario is to disconnect the electronic blood pressure machine and measure the client's blood pressure manually every 15 minutes. Given that the machine is malfunctioning and providing inconsistent readings, relying on manual measurements ensures accuracy and maintains the quality of care. Notifying the manufacturer (Choice A) may be necessary in the long run, but the immediate concern is the accuracy of the vital signs. Adjusting the machine settings again (Choice C) without resolving the underlying issue would not address the problem. Ignoring the extra readings (Choice D) could lead to incorrect assessment and compromise patient care. Therefore, the best course of action is to disconnect the machine and opt for manual blood pressure measurements until the issue is resolved.

Correct Answer: C

Rationale: The correct answer is to recommend the client to use progressive relaxation techniques at bedtime. Progressive relaxation techniques help reduce stress and muscle tension, which can promote better sleep. Choice A, drinking a cup of hot cocoa before bedtime, contains caffeine which can interfere with falling asleep. Choice B, exercising 1 hour before going to bed, can stimulate the body and mind, making it harder to fall asleep. Choice D, reflecting on the day's activities before going to bed, may lead to increased mental activity and prevent relaxation, making it difficult to fall asleep.

Correct Answer: D

Rationale: The correct answer is D: Blood glucose. Monitoring blood glucose levels is crucial for clients receiving total parenteral nutrition (TPN) due to the high glucose content in TPN solutions. TPN delivers essential nutrients, including glucose, directly into the bloodstream. Clients on TPN are at risk of developing hyperglycemia due to the concentrated glucose infusion. Therefore, close monitoring of blood glucose levels is necessary to detect and prevent hyperglycemia-related complications such as osmotic diuresis, hyperosmolarity, and electrolyte imbalances. While serum sodium, serum calcium, and blood urea nitrogen (BUN) levels are important parameters in various clinical scenarios, they are not specifically associated with TPN administration. These values are not the primary indicators to assess for complications in clients receiving TPN.

Correct Answer: A

Rationale: Using tracheostomy covers when outdoors is essential to protect the tracheostomy from dust and debris, reducing the risk of infection. Tracheostomy covers help maintain cleanliness and prevent foreign particles from entering the stoma. Choice B is incorrect because cleaning the tracheostomy with alcohol can be too harsh and drying for the skin surrounding the stoma, leading to skin irritation. Choice C is incorrect as tracheostomy tubes are typically replaced only when clinically indicated or as per the healthcare provider's instructions, not routinely every week, to prevent unnecessary risks and complications. Choice D is incorrect as covering the tracheostomy with a wet cloth when sleeping can create a moist environment ideal for bacterial growth, increasing the risk of infection and skin breakdown. It is important to keep the tracheostomy site clean, dry, and protected to maintain optimal hygiene and prevent complications.

Correct Answer: A

Rationale: Instructing the client to follow a finger through the six cardinal positions of gaze is the correct action when assessing extraocular eye movements. This technique assesses the movement of the eyes in all directions and helps to test cranial nerves 3, 4, and 6, which control eye movements. Choice B is incorrect as the distance mentioned is not relevant for assessing extraocular eye movements. Choice C is incorrect as both eyes need to be assessed independently. Choice D is incorrect as positioning the client 6.1 m (20 feet) away from the Snellen chart is related to visual acuity testing, not extraocular eye movements.

Correct Answer: C

Rationale: Assessing the client's health risks is the priority as it provides essential information to guide subsequent care. By understanding the client's health risks, the nurse can tailor health education and interventions, such as immunizations and lifestyle modifications, to address specific needs. Providing information about immunization against meningitis (Choice A) is important but should come after assessing health risks. Instructing the client to have a TB skin test every 2 years (Choice B) is relevant but not the initial step in care. Teaching about exercise recommendations (Choice D) is also essential but should follow the assessment of health risks.

Correct Answer: B

Rationale: The correct answer is B. Petroleum jelly is flammable and should not be used with oxygen therapy as it can increase the risk of fire. Using petroleum jelly near oxygen can lead to a fire hazard. Choices A, C, and D are correct statements that indicate proper understanding of oxygen therapy safety measures. Choice A emphasizes the importance of keeping the oxygen tank upright to prevent leaks, choice C highlights the necessity of avoiding smoking to prevent exacerbation of COPD, and choice D encourages seeking medical help promptly in case of breathing difficulties.

Correct Answer: B

Rationale: In a client with septicemia, decreased blood pressure is a critical finding that suggests potential septic shock, a life-threatening condition. Septic shock requires immediate medical intervention to prevent further deterioration and organ dysfunction. Increased urine output (Choice A) may indicate adequate fluid resuscitation, which is a positive response. Increased heart rate (Choice C) and increased respiratory rate (Choice D) are common physiological responses to sepsis and do not necessarily indicate immediate life-threatening complications like decreased blood pressure does in septic shock.

Correct Answer: B

Rationale: The correct action for the nurse when assessing the respiratory system for complications of immobility is to auscultate the entire lung region. This approach allows the nurse to identify any diminished breath sounds, crackles, or wheezes that may indicate respiratory issues. Inspecting chest wall movements primarily during the expiratory cycle (Choice A) may not provide a comprehensive assessment of lung sounds. Focusing auscultation on the upper lung fields (Choice C) may miss important findings in the lower lung fields. Assessing the patient at least every 4 hours (Choice D) is important for monitoring overall patient condition but does not specifically address the assessment of respiratory complications related to immobility.
