Correct Answer is C
Explanation
A. Adding Dextrose to a TPN solution may not be appropriate for the immediate management of insulin shock.
B. Mixing the Dextrose in a piggyback solution may dilute the concentration and delay the delivery of glucose, which is not ideal in the acute management of insulin shock.
C. Pushing the undiluted Dextrose slowly through the currently infusing IV allows for rapid administration of glucose to address the hypoglycemia associated with insulin shock.
D. Diluting the Dextrose in a liter of Normal Saline solution would significantly reduce the concentration and delay the delivery of glucose, which is not desirable in the acute management of insulin shock.
Correct Answer is D
Explanation
A. Increasing oral fluid intake is not a recommended treatment for skin flushing caused by tadalafil. Skin flushing is a common side effect and usually resolves on its own without the need for increased fluid intake.
B. Advising the client to take nitroglycerin is inappropriate and potentially dangerous. Tadalafil and nitroglycerin both lower blood pressure, and their combined use can lead to a significant drop in blood pressure, which can be life-threatening.
C. Telling the client to go to the emergency department is unnecessary in this case. Skin flushing is a known side effect of tadalafil and does not typically require emergency medical attention unless accompanied by other severe symptoms.
D. Reassuring the client that skin flushing is a common side effect of tadalafil is appropriate. This side effect is generally mild and temporary, and the client should be informed that it is not a cause for concern.
