A nurse is teaching a client who has a new prescription for lovastatin. Which of the following diagnostic tests should the nurse instruct the client to complete before starting the medication?

Potassium level.

Hemoglobin level.

Kidney function tests.

Liver function tests.

Answer and Explanation

The Correct Answer is D

Choice A rationale:
(Potassium level) Lovastatin is a medication used to treat high cholesterol levels. While potassium levels are important to monitor for certain conditions, they are not directly related to the initiation of lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice B rationale:
(Hemoglobin level) Hemoglobin levels are important to assess for anemia or other blood disorders. However, they are not specifically required before starting lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice C rationale:
(Kidney function tests) While kidney function tests are essential for many medications to ensure proper excretion and avoid toxicity, they are not directly related to the initiation of lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice D rationale:
(Liver function tests) Liver function tests are crucial before starting lovastatin therapy. Lovastatin is metabolized in the liver, and it can potentially cause liver damage or abnormalities in liver enzymes. Monitoring liver function helps detect any pre-existing liver conditions and ensures the safe use of the medication. Therefore, this is the correct choice for diagnostic testing before starting the medication.

Correct Answer is D

Explanation

Choice A rationale:
Poor skin turgor is a sign of dehydration and is not specifically related to hypoglycemia. It is assessed by pinching the skin on the back of the hand and observing how quickly it returns to its normal position.
Choice B rationale:
Fruity breath odor is associated with diabetic ketoacidosis (DKA), a complication of uncontrolled diabetes, not hypoglycemia. It is caused by the presence of ketones in the breath due to the breakdown of fats for energy in the absence of adequate insulin.
Choice C rationale:
Kussmaul respirations are deep, rapid, and labored breathing patterns seen in diabetic ketoacidosis (DKA), not in hypoglycemia. They are the body's attempt to blow off excess carbon dioxide and acid from the blood.
Choice D rationale:
Irritability is a common manifestation of hypoglycemia. Low blood glucose levels can affect brain function, leading to mood changes, irritability, and nervousness.

A. Prepare an endotracheal tube for intubation. B. Insert a plastic oral airway. C. Provide oxygen using a manual resuscitation bag. D. Perform a head-tilt with chin-lift.

Correct Answer is C

Explanation

Choice A rationale:

Preparing an endotracheal tube for intubation is not the first action the nurse should take in this situation. Intubation is an invasive procedure and should be reserved for cases where other, less invasive methods of airway management have failed.

Choice B rationale:

Inserting a plastic oral airway may help maintain the airway in some situations, but it is not the first action to take when the client's airway is obstructing and their oxygen saturation is low.

Choice C rationale:

Providing oxygen using a manual resuscitation bag (bag-valve-mask device) is the correct first action. This allows the nurse to manually assist the client's breathing and deliver oxygen more effectively than just providing supplemental oxygen through a nasal cannula or face mask.

Choice D rationale:

Performing a head tilt with a chin-lift is a basic airway maneuver, but it may not be sufficient in this situation, especially if the airway is completely obstructed. Providing oxygen with a manual resuscitation bag takes precedence.
