Nursing Elites

1. A client who has heart failure is admitted with a serum potassium level of 2.9 mEq/L. Which action is most important for the nurse to implement?

• A. Administer 20 mEq of potassium chloride.
• B. Initiate continuous cardiac monitoring.
• C. Arrange a consultation with the dietitian.
• D. Educate about the side effects of diuretics.

Correct answer: B

Rationale: Hypokalemia, defined as a serum potassium level below the normal range of 3.5 to 5 mEq/L, can lead to changes in myocardial irritability and ECG waveform, potentially causing life-threatening dysrhythmias. Therefore, the priority action for the nurse is to initiate continuous cardiac monitoring to promptly detect any abnormal heart rhythms or ventricular ectopy. This monitoring is crucial for assessing the impact of potassium replacement therapy on the cardiac rhythm and ensuring the safety of the client. While administering potassium chloride is important for correcting the hypokalemia, it should occur after cardiac monitoring is in place. Consulting with a dietitian and educating about diuretic side effects are relevant aspects of care but are not the immediate priority in this situation where cardiac monitoring takes precedence for timely intervention.

2. In the staging process of Hodgkin's disease, what does Stage I indicate?

• A. Involvement of a single lymph node.
• B. Involvement of two or more lymph nodes on the same side of the diaphragm.
• C. Involvement of lymph node regions on both sides of the diaphragm.
• D. Involvement of diffuse disease of one or more extralymphatic organs.

Correct answer: A

Rationale: In the staging process of Hodgkin's disease, Stage I signifies the involvement of a single lymph node. This stage indicates localized disease with the disease being limited to a single lymph node or a group of adjacent nodes. Choices B, C, and D are incorrect because they describe more extensive involvement of lymph nodes, both sides of the diaphragm, or extralymphatic organs, which would correspond to higher stages in the staging system.

3. A client with early breast cancer receives the results of a breast biopsy and asks the nurse to explain the meaning of staging and the type of receptors found on the cancer cells. Which explanation should the nurse provide?

• A. Lymph node involvement is not significant.
• B. Small tumors are aggressive and indicate poor prognosis.
• C. The tumor's estrogen receptor guides treatment options.
• D. Stage I indicates metastasis.

Correct answer: C

Rationale: Treatment decisions and prediction of prognosis are related to the tumor's receptor status, such as estrogen and progesterone receptor status which commonly are well-differentiated, have a lower chance of recurrence, and are receptive to hormonal therapy. Tumor staging designates tumor size and spread of breast cancer cells into axillary lymph nodes, which is one of the most important prognostic factors in early-stage breast cancer.

4. A client with elevated levels of antidiuretic hormone (ADH) triggers the release of this hormone due to which disorder?

• A. Pneumonia
• B. Dehydration
• C. Renal failure
• D. Edema

Correct answer: B

Rationale: Antidiuretic hormone (ADH) increases tubular permeability to water, causing more water absorption into the capillaries. ADH is released in response to a rising extracellular fluid osmolarity, such as in dehydration. Pneumonia, renal failure, and edema do not typically lead to the release of ADH. Pneumonia is an inflammatory lung condition, renal failure affects kidney function, and edema is the accumulation of excess fluid in the tissues, none of which directly stimulate the release of ADH.

5. Which food is most important to encourage a client with osteomalacia to include in a daily diet?

• A. Fortified milk and cereals
• B. Citrus fruits and juices
• C. Green leafy vegetables
• D. Red meats and eggs

Correct answer: A

Rationale: The correct answer is A: Fortified milk and cereals. Osteomalacia is a condition caused by a deficiency in vitamin D. Fortified milk and cereals are rich sources of vitamin D, which is essential for managing osteomalacia. Citrus fruits and juices (choice B) are high in vitamin C, but vitamin D is the primary concern for osteomalacia. Green leafy vegetables (choice C) are good sources of various nutrients but not the main focus for managing osteomalacia. Red meats and eggs (choice D) are good sources of protein and other nutrients but are not as critical as fortified milk and cereals for addressing vitamin D deficiency in osteomalacia.
