1. Which statement best describes electrolytes in intracellular and extracellular fluid?

Correct answer: A

Rationale: Electrolytes are distributed unequally between intracellular and extracellular fluids. Sodium concentration is higher in extracellular fluid, while potassium concentration is higher in intracellular fluid. Therefore, the correct answer is 'There is a greater concentration of sodium in extracellular fluid and potassium in intracellular fluid.' Choices B, C, and D are incorrect because they do not accurately describe the typical distribution of sodium and potassium between intracellular and extracellular fluid.

2. The nurse is assessing the newborn's respirations. Which of these findings would indicate a need for follow-up and further intervention?

Correct answer: D

Rationale: The ideal respiratory rate in a newborn is 30-60 breaths per minute. A respiratory rate of 70 breaths per minute indicates tachypnea and may require intervention. Therefore, a rate of 70 breaths per minute would necessitate follow-up and further intervention. Irregular, abdominal, and shallow respirations are common in newborns and may not necessarily indicate the need for immediate follow-up or intervention.

3. A violation of a patient's confidentiality occurs if two nurses are discussing client information in which of the following scenarios?

Correct answer: D

Rationale: The correct answer is 'In the hallway outside the patient's room.' Discussing client information in a public area like a hallway can potentially breach patient confidentiality as it increases the risk of unauthorized individuals overhearing sensitive information. Choices A, B, and C involve discussing client information with other healthcare professionals in appropriate settings, which are more likely to maintain patient confidentiality compared to discussing in a public space like a hallway. Option D is the correct choice because it highlights a scenario where patient information is at higher risk of exposure to unauthorized individuals, hence violating patient confidentiality.

4. A client had a Caesarean delivery and is postpartum day 1. She asks for pain medication when the nurse enters the room to do her shift assessment. The client states that her pain level is an 8 on a scale of 1 to 10. What should be the nurse's priority of care?

Correct answer: C

Rationale: Pain management is a priority, so the nurse should immediately provide pain medication. However, the nurse should conduct a quick assessment while administering the medication to ensure that a complication, such as hemorrhage, hasn't caused the increased pain. A complete assessment can wait until the pain subsides. Controlling pain will enable the client to move, eliminating other potential complications of delivery and facilitating bonding with the infant. Relaxation techniques can act as an adjunct therapy but by themselves are not usually effective for pain management during the early post-Caesarean period.

5. A client complaining of chest pain is prescribed an intravenous infusion of nitroglycerin (Nitro-Bid). After the infusion is initiated, the occurrence of which symptom warrants the nurse discontinuing an intravenous infusion of nitroglycerin?

Correct answer: D

Rationale: The correct answer is 'Cool clammy skin.' This assessment finding indicates decreased cardiac output that could result from excessive vasodilation. Cool clammy skin is a sign of poor perfusion, suggesting that the blood pressure might be dropping too low. Discontinuing the nitroglycerin infusion is crucial to prevent further complications. Choice A, 'Frontal headache,' is a common side effect of nitroglycerin but not a reason to discontinue the infusion unless severe or persistent. Choice B, 'Orthostatic hypotension,' may occur as a side effect of nitroglycerin but does not necessarily warrant discontinuation unless severe. Choice C, 'Decrease in intensity of chest pain,' is actually an expected therapeutic response to nitroglycerin and indicates improved myocardial perfusion, so it is not a reason to stop the infusion.
