Nursing Elites

1. A 20-year-old female has a prescription for tetracycline. While teaching the client how to take her medicine, the nurse learns that the client is also taking Ortho-Novum oral contraceptive pills. Which instructions should be included in the teaching plan?

• A. The oral contraceptives will decrease the effectiveness of the tetracycline.
• B. Nausea often results from taking oral contraceptives and antibiotics.
• C. Toxicity can result when taking these two medications together.
• D. Antibiotics can decrease the effectiveness of oral contraceptives, so the client should use an alternate method of birth control.

Correct answer: D

Rationale: When antibiotics and oral contraceptives are taken together, the effectiveness of the oral contraceptives can be reduced, increasing the risk of pregnancy. Therefore, it is important to advise the client to use an alternate method of birth control to prevent unintended pregnancy. Choices A, B, and C are incorrect because there is no evidence to suggest that oral contraceptives decrease the effectiveness of tetracycline, cause nausea, or result in toxicity when taken with antibiotics.

2. When medications have an additive, synergistic, or antagonistic effect on a tissue, a ________ reaction has occurred.

• A. pharmaceutical
• B. pharmacodynamic
• C. pharmacokinetic
• D. drug incompatibility

Correct answer: B

Rationale: The correct answer is 'pharmacodynamic.' Pharmacodynamics pertain to the effect of a drug on receptors, explaining how drugs affect tissues. Pharmaceutical reactions refer to chemical reactions between drugs before administration or absorption, not their effect on tissues. Pharmacokinetic reactions involve how the body affects the drug, not the tissue. Drug incompatibilities are essentially pharmaceutical reactions, not the specific effects on tissues seen in pharmacodynamic reactions.

3. Six hours after birth, the infant is found to have an area of swelling over the right parietal area that does not cross the suture line. The nurse should chart this finding as:

• A. A cephalohematoma
• B. Molding
• C. Subdural hematoma
• D. Caput succedaneum

Correct answer: A

Rationale: The correct answer is A, a cephalohematoma. A cephalohematoma is an area of bleeding outside the cranium but beneath the periosteum, typically not crossing the suture line. Answer B, molding, is the overlapping of the bones of the cranium and does not involve bleeding, making it an incorrect choice. Answer C, a subdural hematoma, involves intracranial bleeding and is typically diagnosed through imaging studies like a CAT scan or x-ray. Answer D, caput succedaneum, is characterized by edema that crosses the suture line, unlike the described swelling in this case.

4. A client asks the nurse if all donor blood products are cross-matched with the recipient to prevent a transfusion reaction. Which of the following always requires cross-matching?

• A. packed red blood cells
• B. platelets
• C. plasma
• D. granulocytes

Correct answer: A

Rationale: Corrected Rationale: Packed red blood cells contain antigens and antibodies that must be matched between the donor and recipient to prevent transfusion reactions. Platelets, plasma, and granulocytes do not contain red blood cells, so they do not require cross-matching. Platelets are matched based on ABO compatibility, while plasma and granulocytes are not routinely cross-matched as they lack red cell antigens.

5. The physician orders the antibiotics ampicillin (Omnipen) and gentamicin (Garamycin) for a newly admitted client with an infection. The nurse should:

• A. administer both medications simultaneously.
• B. give the medications sequentially, and flush well between them.
• C. ask the physician or pharmacy which medication to give first and how long to wait before giving the other drug.
• D. start one medication now and begin the other medication in 2-4 hours.

Correct answer: B

Rationale: A client with an infection needs both antibiotics as soon as possible. However, the pH of ampicillin is 8-10, and the pH of gentamicin is 3-5.5, making them incompatible when given together. Flushing well between drugs is necessary to prevent interaction. Choice C is incorrect because the nurse, not the physician or pharmacy, should determine the correct administration sequence. Consulting with the pharmacist is appropriate if uncertain. Choice D is incorrect because delaying the second medication by several hours can slow the treatment of the client's infection, as both antibiotics are needed promptly to address the infection effectively. Therefore, the correct action is to give the medications sequentially and flush well between them to prevent any potential interactions.
