A client with nasal congestion receives a prescription for phenylephrine 10 mg by mouth every 4 hours. Which client condition should the nurse report to the healthcare provider before administering the medication?

Choice A reason: This is not the action that the nurse should implement. Determining Glasgow Coma Scale score is a method of assessing the level of consciousness and neurological function of the client, but it is not a priority intervention in this situation. The client's respiratory rate and oxygen saturation are more critical indicators of the client's condition and the need for immediate action. The nurse should assess the Glasgow Coma Scale score as part of the ongoing evaluation, but it is not the first action.

Choice B reason: This is not the action that the nurse should implement. Initiating cardiopulmonary resuscitation (CPR) is a lifesaving procedure that is performed when the client has no pulse and no breathing, but it is not indicated in this situation. The client has a respiratory rate of 4 breaths/minute, which is very low, but not absent. The client also has an oxygen saturation of 75%, which is very low, but not incompatible with life. The nurse should provide oxygen therapy and ventilatory support to the client, but not CPR.

Choice C reason: This is not the action that the nurse should implement. Preparing to assist with chest tube insertion is a procedure that is done to drain air or fluid from the pleural space and restore lung expansion, but it is not relevant in this situation. The client's respiratory depression is caused by the opioid overdose, not by a pneumothorax or a pleural effusion. The nurse should monitor the client's chest x-ray and lung sounds, but not prepare for chest tube insertion.

Choice D reason: This is the action that the nurse should implement. Administering a second dose of naloxone is the most appropriate and effective intervention in this situation. Naloxone is an opioid antagonist that reverses the effects of opioids, such as respiratory depression, sedation, and hypotension. However, naloxone has a shorter duration of action than most opioids, and it may require repeated doses to maintain the reversal. The nurse should administer a second dose of naloxone if the client's respiratory rate and oxygen saturation do not improve or worsen after the first dose. The nurse should also monitor the client for signs of opioid withdrawal, such as agitation, nausea, or pain.

Choice A reason: This is not the most important laboratory value for the nurse to review. Glucose is a measure of blood sugar levels, and it may be affected by various factors, such as diet, medication, stress, or infection. However, glucose is not directly related to the use of diclofenac or the symptoms of the client. The nurse should monitor the glucose levels for any changes, but it is not the priority.

Choice B reason: This is not the most important laboratory value for the nurse to review. Total protein is a measure of the amount of protein in the blood, and it may reflect the nutritional status, liver function, or kidney function of the client. However, total protein is not directly related to the use of diclofenac or the symptoms of the client. The nurse should monitor the total protein levels for any changes, but it is not the priority.

Choice C reason: This is not the most important laboratory value for the nurse to review. Sodium is a measure of the electrolyte balance in the blood, and it may be affected by fluid intake, fluid loss, or hormonal regulation. However, sodium is not directly related to the use of diclofenac or the symptoms of the client. The nurse should monitor the sodium levels for any changes, but it is not the priority.

Choice D reason: This is the most important laboratory value for the nurse to review. Hemoglobin is a measure of the oxygen-carrying capacity of the blood, and it may indicate the presence of anemia, which is a common adverse effect of diclofenac. Diclofenac can cause gastrointestinal bleeding, which can lead to a decrease in hemoglobin and hematocrit levels. The client's appearance and fatigue may be signs of anemia, which can impair the tissue oxygenation and worsen the client's condition. The nurse should review the hemoglobin levels and report any abnormal findings to the healthcare provider. The nurse should also assess the client for other signs of bleeding, such as melena, hematemesis, or hematuria.
