A nurse is preparing to administer haloperidol 5 mg IM to a client. The amount available is haloperidol 20 mg/mL. How many mL should the nurse administer?

(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.25"]

To calculate the volume of haloperidol solution needed, we can use the formula:

Volume (mL)=Dose (mg)/Concentration (mg/mL)

Given: Dose of haloperidol = 5 mg

Concentration of haloperidol solution = 20 mg/mL

Substituting the given values into the formula:

Volume (mL)=5 mg/20 mg/mL

Volume (mL)=5/20

Volume (mL)=0.25 mL

Rounded to the nearest hundredth, the nurse should administer 0.25 mL of haloperidol solution.

Correct Answer is ["A","C","E"]

Explanation

Fluid excess, also known as fluid overload or hypervolemia, occurs when there is an excessive volume of fluid in the body. The nurse should assess for signs and symptoms of fluid excess, which include the following:

A. Bounding pulse: A bounding pulse, or a pulse that feels unusually strong and forceful, can be a sign of fluid excess. Increased blood volume leads to increased cardiac output, which can manifest as a bounding pulse.

B. Urine-specific gravity greater than 1.030: Urine-specific gravity greater than 1.030 typically indicates concentrated urine and is more indicative of dehydration rather than fluid excess.

C. Pitting edema: Pitting edema occurs when pressure is applied to the skin, resulting in an indentation or "pit" that persists after the pressure is released. It is a classic sign of fluid excess, indicating fluid accumulation in the interstitial spaces.

D. Swelling at the IV site: Swelling at the IV site may indicate infiltration or phlebitis rather than fluid excess. While fluid excess can lead to generalized swelling, swelling specifically at the IV site may suggest a local issue related to the IV infusion.

E. Crackles upon auscultation: Crackles, also known as rales, are abnormal lung sounds heard upon auscultation and are indicative of fluid accumulation in the lungs, which can occur with fluid excess. Crackles are typically heard in the bases of the lungs and may indicate pulmonary edema.

A. Protamine B. Naloxone C. Diphenhydramine D. Flumazenil

Correct Answer is D

Explanation

A. Protamine: Protamine is used as an antidote for heparin, not for benzodiazepines.

B. Naloxone: Naloxone is an opioid antagonist used to reverse the effects of opioids, such as morphine or heroin. It does not antagonize the effects of benzodiazepines.

C. Diphenhydramine: Diphenhydramine is an antihistamine medication commonly used for allergy relief and as a sleep aid. It does not antagonize the effects of benzodiazepines.

D. Flumazenil: Flumazenil is a benzodiazepine receptor antagonist. It is used to reverse the effects of benzodiazepine overdose or to rapidly reverse the sedative effects of benzodiazepines in cases such as anesthesia recovery. Therefore, it is the correct option for antagonizing benzodiazepines.
