Nursing Elites

1. Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?

• A. Ca
• B. K
• C. Na
• D. Cl

Correct answer: B

Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.

2. A nurse is weighing a breastfed 6-month-old infant who has been brought to the pediatrician's office for a scheduled visit. The infant's weight at birth was 6 lb 8 oz. The nurse notes that the infant now weighs 13 lb. What action should the nurse take?

• A. Tell the mother to decrease the daily number of feedings because the weight gain is excessive.
• B. Tell the mother that the infant's weight is increasing as expected.
• C. Tell the mother that the infant should continue with breast milk as the weight gain is adequate.
• D. Tell the mother that semisolid foods should not be introduced until the infant's weight stabilizes.

Correct answer: B

Rationale: The correct answer is to inform the mother that the infant's weight gain is normal. Infants typically double their birth weight by 6 months, which is precisely the case here, with the infant's weight increasing from 6 lb 8 oz to 13 lb. This weight gain indicates healthy growth and development. Therefore, there is no need to decrease feedings. The infant should continue with breast milk as it is providing adequate nutrition. Additionally, introducing semisolid foods is usually recommended between 4 and 6 months of age, so there is no indication to delay based on the infant's weight gain.

3. What is the most common cause of acute renal failure?

• A. Shock
• B. Nephrotoxic drugs
• C. Enlarged prostate
• D. Diabetes

Correct answer: A

Rationale: The most common cause of acute renal failure is shock. In cases of shock, such as hypovolemic shock where there is low blood volume, the kidneys receive inadequate blood flow leading to acute renal failure. This can result in the kidneys starting to die within 20 minutes of low pressure. While nephrotoxic drugs can also cause acute renal failure, shock is more commonly associated with this condition. An enlarged prostate can lead to urinary retention but is not the most common cause of acute renal failure. Diabetes, on the other hand, can cause chronic kidney disease over time but is not typically the primary cause of acute renal failure.

4. A client delivered a term male infant four hours ago. The infant was stillborn. Which room assignment would be most appropriate for this client?

• A. Request a private room on the GYN floor
• B. Assign her to a private room on the postpartum unit
• C. Discharge her home as soon as her condition is stable
• D. Room her with another client who experienced a pregnancy loss

Correct answer: A

Rationale: In this situation, the most appropriate room assignment for the client who delivered a stillborn infant would be to request a private room on the GYN floor. This client needs privacy to grieve, and having a private space allows for family members to offer support. Placing her in a GYN unit ensures that she is away from the maternity unit's sights and sounds, which could be painful reminders for her. Assigning her to a postpartum unit may cause distress due to the presence of other mothers and newborns. Discharging her home too early may not allow her sufficient time for emotional and physical recovery. Rooming her with another client who experienced a pregnancy loss may not provide the necessary privacy and space she needs for her emotional well-being.

5. 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.
