1. A client who had surgery yesterday is becoming increasingly anxious. The client’s respiratory rate has increased to 38 breaths/minute. The client has a nasogastric tube to low intermittent suction with 500 ml of yellow-green drainage over the last four hours. The client's arterial blood gases (ABGs) indicate a decreased CO2 and an increased serum pH. Which serum laboratory value should the nurse monitor first?
- A. Electrolytes.
- B. Creatinine.
- C. Blood urea nitrogen.
- D. Glucose.
Correct answer: A
Rationale: The correct answer is A, Electrolytes. In this scenario, the client is at risk for metabolic alkalosis due to the loss of gastric secretions through the nasogastric tube. Monitoring electrolytes is crucial to assess the levels of sodium, potassium, chloride, and bicarbonate, which are important in maintaining the acid-base balance of the body. Changes in these electrolyte levels can provide valuable information about the client's fluid status and acid-base balance. Creatinine, blood urea nitrogen, and glucose levels are important parameters to monitor in different situations but are not the priority in this case of potential metabolic alkalosis.
2. What is the best position for a client experiencing a nosebleed?
- A. Sitting up and leaning forward
- B. Lying flat with a pillow under the head
- C. Sitting up and leaning back
- D. Lying on the side with the head elevated
Correct answer: A
Rationale: The best position for a client experiencing a nosebleed is sitting up and leaning forward. This position helps prevent blood from flowing down the throat and reduces the risk of aspiration. Choice B is incorrect as lying flat can lead to blood flowing down the throat. Choice C is also incorrect because leaning back may cause blood to flow backward into the throat. Choice D is incorrect as lying on the side with the head elevated is not the optimal position to manage a nosebleed effectively.
3. What most influences the severity of respiratory distress syndrome (RDS)?
- A. Poor cough and gag reflex
- B. The gestational age at birth
- C. Administering high concentrations of oxygen
- D. The sex of the infant
Correct answer: B
Rationale: The correct answer is B. The gestational age at birth most influences the severity of respiratory distress syndrome (RDS). RDS is caused by a deficiency of surfactant and it occurs almost exclusively in preterm, low-birth weight infants. Therefore, the gestational age at birth is a key factor in determining the likelihood and severity of RDS. Choices A, C, and D are incorrect as they do not directly relate to the primary factor influencing the severity of RDS.
4. An adult woman with primary Raynaud phenomenon develops pallor and then cyanosis of her fingers. After warming her hands, the fingers turn red, and the client reports a burning sensation. What action should the nurse take?
- A. Apply a cool compress to the affected fingers for 20 minutes
- B. Secure a pulse oximeter to monitor the client's oxygen saturation
- C. Report the finding to the healthcare provider as soon as possible
- D. Continue to monitor the fingers until the color returns to normal
Correct answer: D
Rationale: In primary Raynaud phenomenon, the fingers go through a color sequence of pallor, cyanosis, and then redness when warmed. The burning sensation reported by the client indicates reperfusion. Continuing to monitor the fingers until the color returns to normal is appropriate in this situation as it ensures that the symptoms are resolving without the need for further intervention. Applying a cool compress could exacerbate the symptoms by causing vasoconstriction. Securing a pulse oximeter to monitor oxygen saturation is not necessary in this case as the issue is related to vasospasm rather than oxygenation. Reporting the finding to the healthcare provider is not urgent unless there are signs of complications or the symptoms do not improve with warming.
5. The nurse reports that a client is at risk for a brain attack (stroke) based on which assessment finding?
- A. Nuchal rigidity
- B. Carotid bruit
- C. Jugular vein distention
- D. Palpable cervical lymph node
Correct answer: B
Rationale: The correct answer is B: Carotid bruit. A carotid bruit is a significant risk factor for stroke as it indicates turbulent blood flow due to narrowing of the carotid artery. Nuchal rigidity is associated with meningitis, jugular vein distention can be a sign of heart failure, and palpable cervical lymph nodes may indicate infection, but they are not directly linked to stroke risk.
