A nurse is caring for a client who has dehydration. Which of the following findings should the nurse expect?
Peripheral edema
Bradycardia
Postural hypotension
Distended neck veins
The Correct Answer is C
Dehydration results from excessive fluid loss or inadequate fluid intake, leading to decreased intravascular volume and impaired tissue perfusion. Clinical manifestations reflect reduced circulating volume and compensatory cardiovascular responses aimed at maintaining blood pressure. A key feature of hypovolemia is orthostatic or postural changes in blood pressure due to inadequate vascular filling when the client changes position. Early recognition of these signs is essential to prevent progression to hypovolemic shock.
Rationale:
A. Peripheral edema is not expected in dehydration because it reflects fluid excess in the interstitial spaces rather than fluid deficit. Edema is commonly associated with conditions such as heart failure, renal impairment, or hypoalbuminemia. In dehydration, fluid volume is reduced, so tissue swelling does not occur.
B. Bradycardia is not typical in dehydration; instead, tachycardia is expected as a compensatory mechanism to maintain cardiac output. The heart rate increases to help preserve perfusion in response to reduced circulating volume. A slow heart rate would be inconsistent with hypovolemic states.
C. Postural hypotension is expected because reduced intravascular volume limits the body’s ability to maintain blood pressure when changing position. When a client stands, gravity causes blood pooling in the lower extremities, and inadequate volume results in a drop in cerebral perfusion. This leads to dizziness, lightheadedness, and potential syncope, making it a hallmark sign of dehydration.
D. Distended neck veins are associated with fluid overload states such as heart failure or fluid retention, not dehydration. In hypovolemia, jugular venous pressure is typically low or flat due to reduced circulating blood volume. Therefore, this finding is inconsistent with dehydration.

Explanation
This question focuses on identifying manifestations of opioid-induced respiratory depression following IV morphine administration. Morphine is an opioid analgesic that depresses the central nervous system and can suppress the respiratory drive, especially in postoperative clients who are already sedated from anesthesia. Findings such as somnolence, pinpoint pupils, bradypnea, hypotension, and decreased respiratory effort are classic indicators of opioid toxicity. Early recognition is critical because progressive respiratory depression can rapidly lead to hypoxia, respiratory arrest, and cardiovascular collapse.
Rationale for Correct findings:
• Decreased respiratory effort, bilateral crackles: Decreased respiratory effort following morphine administration is a serious sign of opioid-induced respiratory depression. Opioids suppress the medullary respiratory center, leading to slower and shallower breathing that reduces oxygen exchange. Bilateral crackles may indicate retained secretions, atelectasis, or developing pulmonary complications due to hypoventilation. This finding requires immediate nursing intervention, including respiratory assessment, oxygen support, and possible naloxone administration.
• Somnolent: Excessive somnolence is an early neurologic indicator of opioid oversedation and can precede respiratory arrest. A client who becomes increasingly difficult to arouse may not maintain adequate airway protection or respiratory effort. Monitoring the level of consciousness is essential because declining neurologic responsiveness correlates closely with worsening respiratory depression. Immediate reassessment and provider notification are warranted.
• Pinpoint pupils: Pinpoint pupils, or miosis, are a classic manifestation of opioid effects on the central nervous system. In the postoperative setting, this finding strongly suggests excessive opioid activity, particularly when accompanied by sedation and bradypnea. Although miosis alone may not be dangerous, it becomes clinically significant when occurring alongside respiratory depression. This finding helps confirm suspected opioid toxicity and requires prompt evaluation.
• Respiratory rate 10/min: A respiratory rate of 10/min is abnormally low and indicates bradypnea, which is a major concern after opioid administration. Respiratory depression is one of the most dangerous adverse effects of morphine because inadequate ventilation can lead to carbon dioxide retention and hypoxemia. A declining respiratory rate often precedes respiratory arrest if untreated. Immediate assessment and intervention are necessary to prevent deterioration.
• Blood pressure 98/58 mm Hg: Hypotension can occur with morphine because opioids cause peripheral vasodilation and reduce sympathetic nervous system activity. The client’s blood pressure has dropped significantly from baseline, suggesting a clinically important hemodynamic effect. Combined with sedation and respiratory depression, hypotension may indicate worsening opioid toxicity. Reduced perfusion can compromise oxygen delivery to vital organs and requires urgent monitoring and management.
Rationale for incorrect findings:
• S1, S2, no murmur, bradycardia: A heart rate of 58/min represents mild bradycardia, which can occur postoperatively or secondary to opioid administration. While it should continue to be monitored, it is less immediately dangerous than respiratory depression or altered consciousness. The absence of murmurs or abnormal heart sounds suggests no acute structural cardiac complication.
• Temperature 37.4° C (99.4° F): A temperature of 37.4°C is within a mild postoperative range and does not indicate acute infection or severe systemic complication. Slight elevations in temperature can occur after surgery because of inflammation or stress response. Compared with the client’s respiratory and neurologic changes, this finding is not immediately life-threatening. Ongoing monitoring is appropriate, but urgent intervention is not required based on temperature alone.
• Heart rate 58/min: Although slightly below normal, a heart rate of 58/min is not as critical as the client’s low respiratory rate and decreased responsiveness. Mild bradycardia may occur due to opioid effects, vagal stimulation, or postoperative relaxation. Since perfusion is still being maintained and no dysrhythmias are described, it is a secondary concern at this time. Airway and breathing abnormalities take priority over circulation in this scenario.
Correct Answer is A
Explanation
Care planning for a client with dysphagia focuses on reducing aspiration risk and promoting safe swallowing during oral intake. Dysphagia, often associated with neurological or structural impairment, affects the coordination of swallowing mechanisms and increases the likelihood of food or fluids entering the airway. Nursing interventions prioritize positioning techniques, diet modifications, and swallowing strategies that protect the airway while maintaining adequate nutrition and hydration.
Rationale:
A. Tilting the head forward during meals, also known as the chin-tuck position, helps protect the airway by narrowing the opening of the trachea and directing food toward the esophagus. This positioning improves swallowing safety and reduces the risk of aspiration in clients with Dysphagia. It is a commonly recommended technique during feeding.
B. Elevating the head of the bed to 30° is insufficient for safe swallowing in clients with dysphagia. The recommended position during meals is typically high Fowler’s (at least 60–90°) to promote proper swallowing and reduce aspiration risk. A 30° elevation does not provide adequate airway protection during feeding.
C. Providing three large meals per day is inappropriate because clients with dysphagia are at higher risk of fatigue and aspiration during prolonged or large-volume meals. Smaller, more frequent meals with appropriate texture modifications are preferred to ensure safe intake and reduce swallowing difficulty.
D. Encouraging socialization during mealtimes is not a priority intervention for dysphagia management. While social interaction may support emotional well-being, it does not directly address swallowing safety. The primary focus remains on airway protection and safe feeding techniques.
