1. After a myocardial infarction, why is the hospitalized client taught to move the legs while resting in bed?

Correct answer: C

Rationale: The correct answer is C. Moving the legs helps prevent thrombophlebitis and blood clot formation by promoting venous return in clients on bed rest. This prevents stasis and clot formation in the lower extremities. Choices A, B, and D are incorrect because the primary goal of moving the legs is to prevent thrombophlebitis and blood clot formation, rather than preparing for ambulation, promoting elimination, or decreasing pressure ulcer formation. Ambulation preparation involves different exercises, urinary and intestinal elimination are not directly related to leg movements, and pressure ulcer prevention is more related to repositioning and skin care.

2. The patient is being educated on taking hydrochlorothiazide. Which statement by the patient indicates a need for further teaching?

Correct answer: A

Rationale: The correct answer is A because patients do not require extra sodium or calcium while taking hydrochlorothiazide, a thiazide diuretic. This medication actually promotes the excretion of sodium and water. Choices B, C, and D are correct statements regarding the use of hydrochlorothiazide. Patients are encouraged to have a diet rich in fruits and vegetables, be careful with position changes due to potential orthostatic hypotension, and take the medication in the morning to reduce the need for frequent urination during nighttime.

3. A client receives a prescription for 1 liter of lactated Ringer's intravenously to be infused over 6 hours. How many mL/hr should the nurse program the infusion pump to deliver? (Enter numerical value only. If rounding is needed, round to the nearest whole number.)

Correct answer: A

Rationale: The correct infusion rate is 167 mL/hr. This is calculated by dividing the total volume (1000 mL) by the total time (6 hours), resulting in 166.67 mL/hr, which should be rounded to the nearest whole number as 167 mL/hr. This calculation ensures a steady infusion rate over the specified time frame. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation based on the volume and time provided in the prescription.

4. A 32-year-old female client complains of severe abdominal pain each month before her menstrual period, painful intercourse, and painful defecation. Which additional history should the nurse obtain that is consistent with the client's complaints?

Correct answer: B

Rationale: The correct answer is B: 'Inability to get pregnant.' The symptoms described in the client's complaints, which include severe abdominal pain before menstruation, painful intercourse, and painful defecation, are indicative of endometriosis. Endometriosis is a condition characterized by the abnormal presence of endometrial tissue outside the uterus, commonly leading to infertility. While choices A, C, and D may be associated with other conditions, they are not directly related to the symptoms described by the client, making them incorrect choices. Frequent urinary tract infections may suggest a different issue, premenstrual syndrome does not typically present with severe abdominal pain, and chronic use of laxatives is not a typical symptom of endometriosis.

5. The nurse is preparing to administer amoxicillin (Amoxil) to a patient and learns that the patient previously experienced a rash when taking penicillin. Which action will the nurse take?

Correct answer: C

Rationale: When a patient has a history of rash from penicillin, it indicates a potential allergic reaction to penicillin and other related drugs, such as amoxicillin. It is crucial to avoid administering penicillins to such patients unless there is no alternative. The nurse's best action in this situation is to contact the provider to discuss using a different antibiotic from a different class. This approach helps prevent potential severe allergic reactions. While epinephrine and antihistamines are used to manage allergic reactions, administering amoxicillin despite the known allergy is not advisable and could lead to serious consequences. Requesting a beta-lactamase-resistant drug does not address the issue of potential allergic reactions in this scenario.
