1. In the treatment of symptomatic bradycardia, which medication is most commonly recognized?

• A. Questran
• B. Digitalis
• C. Nitroglycerin
• D. Atropine

Correct answer: D

Rationale: Atropine is the medication most commonly recognized for the treatment of symptomatic bradycardia because it increases the rate of conduction in the AV node, helping to alleviate bradycardia. Questran is a medication used to lower cholesterol levels and is not indicated for bradycardia. Digitalis, such as Digoxin, is used for heart failure and atrial fibrillation but not typically for bradycardia. Nitroglycerin is primarily used for angina and not bradycardia.

2. The client diagnosed with end-stage liver disease has completed an advance directive and a do-not-resuscitate (DNR) document and wishes to receive palliative care. Which of the following would correspond to the client's wish for comfort care?

• A. Positioning frequently to prevent skin breakdown and providing pain management and other comfort measures
• B. Carrying out vigorous resuscitation efforts if the client were to stop breathing, but no resuscitation if the heart stops beating
• C. Providing intravenous fluids when the client becomes dehydrated
• D. Providing total parenteral nutrition (TPN) if the client is not able to eat

Correct answer: A

Rationale: Palliative care includes measures to prevent skin breakdown, pain management, and management of other symptoms that cause discomfort, as well as encouraging contact with family and friends. A DNR request precludes all resuscitative efforts related to respiratory or cardiac arrest, making choice B incorrect. Dehydration is a natural part of the dying process, so providing intravenous fluids as in choice C would not align with the client's wish for comfort care. Total parenteral nutrition (TPN) as in choice D is an invasive procedure meant to prolong life and is not part of palliative care, which focuses on improving quality of life rather than extending it.

3. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

• A. It protects the bacteria from antibiotic and immunologic destruction.
• B. Glycocalyx neutralizes the antibiotic, rendering it ineffective.
• C. It competes with the antibiotic for binding sites on the microbe.
• D. Glycocalyx provides nutrients for microbial growth.

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.

4. A woman is in the active phase of labor. An external monitor has been applied, and a fetal heart deceleration of uniform shape is observed, beginning just as the contraction is underway and returning to the baseline at the end of the contraction. Which of the following nursing actions is most appropriate?

• A. Administer O2.
• B. Turn the client on her left side.
• C. Notify the physician.
• D. No action is necessary

Correct answer: D

Rationale: This scenario describes early deceleration due to head compression, which is a benign finding in labor. Early decelerations mirror the contractions and do not require any intervention as they are considered a normal response to fetal head compression. The fetal heart rate returns to baseline at the end of the contraction. In this case, the correct action is no action at the moment. Close monitoring of the mother and baby is essential, but immediate intervention is not required. Administering O2 (Choice A) or turning the client on her left side (Choice B) is not indicated for early decelerations. Notifying the physician (Choice C) is unnecessary for this type of deceleration.

5. A client has a 10% dextrose in water IV solution running. He is scheduled to receive his antiepileptic drug, phenytoin (Dilantin), at this time. The nurse knows that the phenytoin:

• A. is given after the D10W is finished.
• B. should be given at the time it is due in the medication port closest to the client.
• C. can be piggybacked into the D10W solution now.
• D. is incompatible with dextrose solutions.

Correct answer: D

Rationale: Phenytoin is incompatible with dextrose solutions as they will precipitate when mixed together. Therefore, it should not be piggybacked into the D10W solution or given through the same port. Instead, normal saline should be used to flush before and after administering phenytoin to prevent any interaction with the dextrose solution. Delaying the administration of an antiepileptic drug like phenytoin to maintain therapeutic blood levels is not recommended, so it should not be given after the D10W is finished or based on the medication port closest to the client. Choice A is incorrect because administering phenytoin after the D10W is finished is not the correct approach due to the incompatibility with dextrose solutions. Choice B is incorrect as the timing of phenytoin administration should not be based on the medication port closest to the client but on compatibility considerations. Choice C is incorrect as piggybacking phenytoin into the D10W solution is not advisable due to the incompatibility issue.
