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. A nurse is assessing the status of a client with diabetes mellitus. The nurse concludes that the client is exhibiting adequate diabetic control if the serum level of glycosylated hemoglobin A1C (HbA1C) is less than:

• A. 7%
• B. 9%
• C. 10%
• D. 15%

Correct answer: A

Rationale: The correct answer is A: 7%. Glycosylated hemoglobin A1C (HbA1C) level of 7.0% or less is considered indicative of adequate diabetic control. This level reflects good long-term blood sugar management. Choices B, C, and D are incorrect because an HbA1C level above 7% indicates poor diabetic control and an increased risk of complications associated with diabetes, such as cardiovascular disease, neuropathy, and retinopathy.

3. In assessing cancer risk, which woman is at greatest risk of developing breast cancer?

• A. A 35-year-old multipara who never breastfed.
• B. A 50-year-old whose mother had unilateral breast cancer.
• C. A 55-year-old whose mother-in-law had bilateral breast cancer.
• D. A 20-year-old whose menarche occurred at age 9.

Correct answer: B

Rationale: The correct answer is B because family history of breast cancer, specifically in the mother, is a significant risk factor for developing breast cancer. The age of 50 is also a risk factor for breast cancer. Choice A is less likely as breastfeeding can actually reduce the risk of breast cancer. Choice C is less relevant since the risk is higher with a direct family member. Choice D, although early menarche is a risk factor, the age of the individual is much lower compared to the other age-related risk factors.

4. A client has made an appointment for her annual Papanicolaou test (a.k.a. Pap smear). The nurse who schedules the appointment should tell the client that:

• A. The test cannot be performed while the client is menstruating
• B. Vaginal douching is required at least 24 hours before the test
• C. Spicy foods should not be eaten on the day of the test
• D. The test has absolutely no discomfort associated with it

Correct answer: A

Rationale: The correct answer is A. A Pap smear cannot be performed with accurate results during menstruation. Menstrual blood may interfere with the test results. Choice B is incorrect as vaginal douching should be avoided for at least 24 hours before the test to prevent altering the cervical cells. Choice C is incorrect as there is no restriction on spicy foods before a Pap smear. Choice D is incorrect as some women may experience mild discomfort during the test, although it is generally well-tolerated.

5. An adult female client has undergone a routine health screening in the clinic. Which of the following values indicates to the nurse who receives the report of the client’s laboratory work that the client’s hematocrit is normal?

• A. 10%
• B. 22%
• C. 30%
• D. 43%

Correct answer: D

Rationale: The normal hematocrit for an adult female client ranges from 35% to 47%. A hematocrit value of 43% falls within this normal range, indicating normal levels of red blood cells. Choices A, B, and C are low hematocrit values and are considered below the normal range for adult females, signifying potential anemia or other health issues.
