Acquired resistance is:
substance that can inhibit the growth of bacteria
ability of an organism to cause disease in humans
the severity of a disease that an organism is able to cause
when a microbe is no longer affected by a drug following treatment with an anti-infective
The Correct Answer is D
A. Substance that can inhibit the growth of bacteria: This describes an antibiotic, not acquired resistance.
B. Ability of an organism to cause disease in humans: This describes pathogenicity, not acquired resistance.
C. The severity of a disease that an organism is able to cause: This describes virulence, not acquired resistance.
D. When a microbe is no longer affected by a drug following treatment with an anti-infective: This is the correct definition of acquired resistance. Over time, microbes can develop mechanisms to evade the effects of antibiotics, rendering them ineffective.

Correct Answer is D
Explanation
A. "Have you noticed any blood in your stool?" While this could be a symptom of a severe reaction, it's not the most immediate concern for an allergic reaction.
B. "Are you having difficulty with your hearing?" Hearing problems are not typical symptoms of an antibiotic allergy.
C. "Do you have a headache?" Headaches can occur with various conditions, including allergic reactions, but it's not the most concerning symptom in this case.
D. "Are you having any difficulty breathing?" Difficulty breathing can be a sign of a severe allergic reaction (anaphylaxis) and requires immediate intervention. This is the most critical symptom to assess for.
Correct Answer is ["0.1"]
Explanation
To calculate the volume of haloperidol 5 mg to administer, we'll use the formula:
Volume (mL)=Dose (mg)/Concentration (mg/mL)
Given:
Dose = 5 mg
Concentration = 50 mg/mL
Plugging these values into the formula:
Volume (mL)=5 mg÷50 mg/mL
Volume (mL)=1÷10
So, the nurse should administer 0.1 mL of haloperidol per dose.
