A nurse is assisting in the care of a client who is in the second stage of labor. Which of the following findings should the nurse report to the provider?

Choice A rationale :

The correct answer is A. Calcium gluconate. The nurse should administer calcium gluconate in this situation because the client's respiratory rate is 8/min, which indicates respiratory depression. Magnesium sulfate is known to cause respiratory depression as a side effect, and calcium gluconate is the antidote for magnesium sulfate toxicity. Calcium gluconate works by antagonizing the effects of magnesium on the neuromuscular junction and restoring normal respiratory function. Prompt administration of calcium gluconate can help reverse respiratory depression and prevent further complications.

Choice B rationale

Naloxone. Naloxone is not the correct choice in this scenario. Naloxone is an opioid antagonist and is used to reverse the effects of opioids in cases of opioid overdose. Since the client is receiving magnesium sulfate, which is not an opioid, naloxone would not be effective in reversing the respiratory depression caused by magnesium sulfate. Administering naloxone in this situation would not address the underlying cause and may not improve the client's condition.

Choice C rationale

Flumazenil. Flumazenil is not the correct choice in this situation. Flumazenil is a benzodiazepine antagonist and is used to reverse the effects of benzodiazepines in cases of benzodiazepine overdose. Since the client is not receiving benzodiazepines but rather magnesium sulfate, flumazenil would not be effective in treating the respiratory depression caused by magnesium sulfate. Using flumazenil in this context would not be appropriate and could potentially lead to adverse effects.

Choice D rationale

Protamine sulfate. Protamine sulfate is not the correct choice in this scenario. Protamine sulfate is an antidote for heparin overdose, not for magnesium sulfate toxicity. It works by neutralizing the effects of heparin and preventing further anticoagulation. Since the client's issue is respiratory depression caused by magnesium sulfate, administering protamine sulfate would not be helpful and would not address the primary problem.

Choice A rationale:
0.25 mL - The nurse should not administer 0.25 mL because the available concentration of vitamin K injection is 1 mg/0.5 mL. To achieve the prescribed dose of 1 mg, administering only 0.25 mL would be insufficient.
Choice B rationale:
0.5 mL - This is the correct choice. The nurse should administer 0.5 mL of the vitamin K injection to deliver 1 mg of vitamin K, as the concentration of the injection is 1 mg/0.5 mL. By giving the full 0.5 mL, the newborn will receive the appropriate 1 mg dose.
Choice C rationale:
0.75 mL - Administering 0.75 mL would be excessive for the prescribed 1 mg dose of vitamin K. It is unnecessary to give a higher volume than required, as it could lead to potential adverse effects or wastage.
Choice D rationale:
1 mL - Similarly, administering the entire 1 mL of the vitamin K injection would result in doubling the prescribed dose, leading to potential overdose and adverse reactions. The nurse should avoid administering more than the necessary 0.5 mL.
