Nursing Elites

1. A client with a history of peptic ulcer disease arrives in the emergency department complaining of weakness and states that he vomited 'a lot of dark coffee-looking stomach contents.' The client is cool and moist to the touch. BP 90/50, HR 110, RR 20, T 98. Of the following physician orders, which will the nurse perform first?

• A. Initiate oxygen at 2 liters/nasal cannula.
• B. Start an IV of NS at 150 ml/hr
• C. Insert NG tube to low suction
• D. Attach the client to the ECG monitor

Correct answer: A

Rationale: The correct answer is to initiate oxygen at 2 liters/nasal cannula. The client is presenting signs of shock with hypotension, tachycardia, and cool, moist skin, which indicate poor tissue perfusion. Oxygen should be administered first to improve tissue oxygenation. While all interventions are important, oxygenation takes priority in the ABCs of emergency care. Starting an IV of NS, inserting an NG tube, and attaching the client to the ECG monitor are necessary interventions but should follow the priority of oxygen administration in this scenario.

2. What is pica?

• A. dependency on alcohol
• B. increased iron in the diet
• C. the sickle cell trait
• D. eating ice

Correct answer: D

Rationale: Pica is a disorder characterized by the ingestion of nonfood substances, which can lead to a clinical iron deficiency. It may be the first sign of an underlying issue. Individuals with pica consume a variety of nonfood items such as ice, clay, dirt, or paste. Choice A, dependency on alcohol, is incorrect as it is not related to pica. Choice B, increased iron in the diet, is incorrect because pica involves ingesting nonfood items rather than having an increased intake of iron. Choice C, the sickle cell trait, is unrelated to pica and is therefore incorrect.

3. With a breech presentation, the nurse must be particularly alert for which of the following?

• A. quickening
• B. ophthalmia neonatorum
• C. pica
• D. prolapsed umbilical cord

Correct answer: D

Rationale: With a breech presentation, the nurse must be particularly alert for a prolapsed umbilical cord. Prolapsed umbilical cord is a critical emergency situation where the umbilical cord descends into the vagina before the fetal presenting part, leading to compression between the presenting part and the maternal pelvis. This compression can compromise or completely cut off fetoplacental perfusion, endangering the fetus. Immediate delivery should be attempted to save the fetus. Quickening refers to fetal movements felt by the mother, ophthalmia neonatorum is an eye infection in newborns, and pica is a condition characterized by cravings for non-nutritive substances, none of which are directly related to the risks associated with a breech presentation and prolapsed umbilical cord.

4. Elderly persons with pernicious anemia should be instructed:

• A. to increase their dietary intake of foods high in B12.
• B. that they do not need to return for follow-up for at least a month after initiation of treatment.
• C. that oral B12 is safer and less expensive than parenteral replacement.
• D. that diarrhea can be a transient side effect of B12 injections.

Correct answer: D

Rationale: Elderly persons with pernicious anemia, a condition characterized by vitamin B12 deficiency due to lack of intrinsic factor, should be informed about the potential side effects of B12 injections. Diarrhea is a known transient side effect of B12 injections, along with pain and burning at the injection site, and peripheral vascular thrombosis. Increasing dietary intake of B12-rich foods would not be sufficient due to the malabsorption issue in pernicious anemia. Follow-up is essential in managing pernicious anemia, so instructing patients they do not need to return for follow-up is incorrect. While oral B12 may be a suitable option for some cases, it is not the preferred choice for pernicious anemia where malabsorption is the primary issue.

5. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.
