A client is ordered to receive a bolus of 200 mL of NSS in 35 minutes. At what rate should the nurse set the IV pump? (Use a preceding zero if necessary. Do not use trailing zeros. Round to the nearest tenth if necessary)

A. Decrease in blood pressure: Nitroglycerin can cause vasodilation, leading to a decrease in blood pressure. However, the goal of administering nitroglycerin during an acute myocardial infarction (MI) is not primarily to lower blood pressure, but to improve oxygen supply to the heart and relieve pain. A decrease in blood pressure may occur as a side effect but is not the primary indication for its use.

B. Decrease in cardiac dysrhythmias: While nitroglycerin may help reduce myocardial oxygen demand, it is not specifically aimed at treating or preventing cardiac dysrhythmias. The primary action of nitroglycerin is to relieve chest pain by vasodilation and improving blood flow to the heart muscle.

C. Relief of chest pain: The primary effect of nitroglycerin in the setting of an acute MI is to relieve chest pain (angina). It works by dilating coronary arteries and improving blood flow to the heart muscle, thus reducing ischemia and relieving pain.

D. Decrease in heart rate: Nitroglycerin may have a secondary effect of reducing heart rate due to a reduction in preload and afterload, but this is not the primary objective. Nitroglycerin’s main goal is to relieve chest pain by improving oxygen supply to the heart muscle.

A. The ABG results are pH 7.41, PaO2 93, PaCO2 35, and HCO3 24: These ABG values are all within normal ranges:
pH 7.35–7.45 (normal)
PaO2 80–100 mmHg (normal)
PaCO2 35–45 mmHg (normal)
HCO3 22–26 mEq/L (normal)
These results indicate stable respiratory function and do not warrant immediate intervention.
B. The client's pulse oximeter reading is 91% with a consistent waveform: While 91% is slightly lower than the ideal oxygen saturation (usually above 92%–94%), it is still above the critical threshold of 90%. This could be an acceptable level in some patients on a ventilator, particularly if there are no signs of distress or other abnormalities.
C. There is no manual resuscitation bag at the client's bedside: This is a critical situation. A manual resuscitation bag (Ambu bag) is essential for emergency resuscitation if the ventilator fails or if there is an unexpected issue with the patient's airway. Not having a manual resuscitation bag at the bedside is a safety concern that warrants immediate intervention, as it could delay life-saving measures in an emergency.
D. The patient is receiving continuous IV sedation at 150 mL/hr. There's currently 100 mL remaining of the infusion: While it's important to monitor IV sedation infusions, this situation does not immediately warrant intervention. The nurse can track the remaining infusion and ensure there is an adequate supply or order a new infusion if necessary.
