Nursing Elites

1. You are performing an admission assessment on an older adult patient newly admitted for end-stage liver disease. What principle should guide your assessment of the patients skin turgor?

• A. Overhydration is common among healthy older adults.
• B. Dehydration causes the skin to appear spongy
• C. Inelastic skin turgor is a normal part of aging
• D. Skin turgor cannot be assessed in patients over 70.

Correct answer: C

Rationale:

2. The nurse is assessing the patient for the presence of a Chvostek's sign. What electrolyte imbalance does a positive Chvostek's sign indicate?

• A. Hypermagnesemia
• B. Hypomagnesemia
• C. Hypocalcemia
• D. Hyperkalemia

Correct answer: C

Rationale: Chvostek's sign is characterized by a brief contraction of the upper lip, nose, or side of the face and is indicative of hypocalcemia, making choice C the correct answer. Hypomagnesemia (choice B) is associated with Trousseau's sign, not Chvostek's sign. Hypermagnesemia (choice A) is not related to Chvostek's sign. Hyperkalemia (choice D) is not typically associated with Chvostek's sign; instead, it may present with muscle weakness and cardiac arrhythmias.

3. A client at risk for mild hypernatremia is being taught by a nurse. Which statement should the nurse include in this client's teaching?

• A. Weigh yourself every morning and every night
• B. Check your radial pulse twice a day
• C. Read food labels to determine sodium content
• D. Bake or grill the meat rather than frying it

Correct answer: C

Rationale: The correct answer is to 'Read food labels to determine sodium content.' This is important for a client at risk for mild hypernatremia because monitoring sodium intake is crucial in managing this condition. Choice A is not directly related to managing hypernatremia. Choice B focuses on pulse monitoring, which is not specific to managing sodium levels. Choice D addresses cooking methods, which can be beneficial but is not as directly related to sodium intake monitoring as reading food labels.

4. Electrolytes:

• A. do not form when glucose is added to water.
• B. dissociate in water solutions, but do not form ions.
• C. form ions in water solutions, but do not necessarily dissociate.
• D. dissociate in water solutions and form ions in water solutions.

Correct answer: D

Rationale: The correct answer is D. Electrolytes are substances that dissociate into ions when dissolved in water, allowing the solution to conduct electricity. Choice A is incorrect because glucose does not form electrolytes when added to water. Choice B is incorrect as it states that electrolytes dissociate but do not form ions, which is inaccurate as electrolytes do form ions in water solutions. Choice C is also incorrect as it states that electrolytes form ions but may not necessarily dissociate, which goes against the definition of electrolytes that must dissociate into ions for conductivity. Therefore, choice D is the most accurate as it correctly describes that electrolytes dissociate in water solutions and form ions, highlighting the essential characteristics of electrolytes.

5. What is the main force that pushes fluid in blood capillaries?

• A. Blood pressure.
• B. Sodium in the blood plasma.
• C. Sodium in the interstitial fluid.
• D. Protein in the blood plasma.

Correct answer: A

Rationale: The correct answer is A, blood pressure. Blood pressure is the primary force that pushes fluid out of the capillaries into the surrounding tissues. This pressure difference is essential for the exchange of nutrients, gases, and waste products between the blood and tissues. Choices B, C, and D are incorrect as they do not represent the primary force responsible for pushing fluid in blood capillaries.
