A nurse is caring for a client who is prescribed tetracycline 2 grams daily PO in four divided doses every 6 hr. Available is tetracycline 250 mg capsules. How many capsules should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

To calculate the number of capsules that the nurse should administer per dose, the nurse should first divide the total daily dose of tetracycline by the number of doses per day. This gives the dose per administration:

2 grams / 4 doses = 0.5 grams per dose

Next, the nurse should convert the dose from grams to milligrams, since the available capsules are in milligrams. There are 1000 milligrams in one gram, so the nurse should multiply the dose by 1000:

0.5 grams x 1000 mg/g = 500 mg per dose

Finally, the nurse should divide the dose in milligrams by the strength of each capsule, which is 250 mg. This gives the number of capsules that the nurse should administer per dose:

500 mg / 250 mg/capsule = 2 capsules per dose

Therefore, the nurse should administer 2 capsules of tetracycline every 6 hours to the client.

Correct Answer is D

Explanation

A. Dental erosion can occur due to conditions like gastroesophageal reflux disease (GERD) or frequent vomiting, but it is not a characteristic feature of anorexia nervosa.

B. Hyperactive bowel sounds are not specific to anorexia nervosa and may be seen in various gastrointestinal disorders.

C. Hypertension is not a common finding in individuals with anorexia nervosa. In fact, hypotension (low blood pressure) is more commonly observed due to decreased cardiac output related to malnutrition and electrolyte imbalances.

A. Regression B. Conversion C. Projection D. Undoing

Correct Answer is C

Explanation

A. Regression: Incorrect

Regression is a defense mechanism in which a person reverts to an earlier stage of development in response to stress or anxiety. For example, an adult might start behaving like a child when faced with a difficult situation. In this case, the student berating the teacher doesn't demonstrate a return to an earlier developmental stage, so regression is not the correct choice.

B. Conversion: Incorrect

Conversion refers to the conversion of emotional distress into physical symptoms, such as experiencing physical pain without any apparent physical cause. This mechanism is often seen in conditions like conversion disorder. The student berating the teacher is not exhibiting physical symptoms as a response to emotional distress, so conversion is not the correct choice.

C. Projection: Correct

Projection is the act of attributing one's own unacceptable feelings or thoughts to another person. In this scenario, the student is projecting their own failure onto the teacher and the course by blaming them for the failure. They are unable to accept their own role in the failure and are instead placing the blame on external factors. This aligns with the behavior described in the scenario.

D. Undoing: Incorrect

Undoing involves trying to compensate for or negate an unacceptable action or thought with a contrary action. For instance, someone who had angry thoughts might engage in excessive acts of kindness to "undo" those thoughts. The student berating the teacher is not engaging in actions to negate their negative feelings or thoughts; they are expressing their frustration directly.
