Nursing Elites

1. A client is admitted to the critical care unit after suffering from a massive cerebral vascular accident. The client's vital signs include BP 160/110, HR 42, Cheyne-Stokes respirations. Based on this assessment, the nurse anticipates the client to be in which acid-base balance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.

2. With a breech presentation, the nurse must be particularly alert for which of the following?

• A. quickening
• B. ophthalmia neonatorum
• C. pica
• D. prolapsed umbilical cord

Correct answer: D

Rationale: With a breech presentation, the nurse must be particularly alert for a prolapsed umbilical cord. Prolapsed umbilical cord is a critical emergency situation where the umbilical cord descends into the vagina before the fetal presenting part, leading to compression between the presenting part and the maternal pelvis. This compression can compromise or completely cut off fetoplacental perfusion, endangering the fetus. Immediate delivery should be attempted to save the fetus. Quickening refers to fetal movements felt by the mother, ophthalmia neonatorum is an eye infection in newborns, and pica is a condition characterized by cravings for non-nutritive substances, none of which are directly related to the risks associated with a breech presentation and prolapsed umbilical cord.

3. Which of the following classifications of medications is used to help decrease tremors for clients with hyperthyroidism?

• A. Steroids
• B. Anticonvulsants
• C. Beta blockers
• D. Iodine compounds

Correct answer: C

Rationale: The correct answer is Beta blockers. Beta blockers are commonly used to help decrease tremors in clients with hyperthyroidism by blocking the action of adrenaline. This helps to control symptoms such as rapid heart rate, tremors, and anxiety. Steroids (Choice A) are not typically used to treat tremors in hyperthyroidism. Anticonvulsants (Choice B) are primarily used to control seizures and are not the first-line treatment for tremors in hyperthyroidism. Iodine compounds (Choice D) are used in the treatment of hyperthyroidism by reducing the production of thyroid hormones but are not specifically indicated for tremor relief.

4. A client comes to the clinic for assessment of his physical status and guidelines for starting a weight-reduction diet. The client's weight is 216 pounds and his height is 66 inches. The nurse identifies the BMI (body mass index) as:

• A. Within normal limits, so a weight-reduction diet is unnecessary.
• B. Lower than normal, so education about nutrient-dense foods is needed.
• C. Indicating obesity because the BMI is 35.
• D. Indicating overweight status because the BMI is 27.

Correct answer: C

Rationale: Obesity is defined by a BMI of 30 or more with no co-morbid conditions. Body Mass Index (BMI) is calculated by utilizing a chart or nomogram that plots height and weight. In this case, the client's BMI is calculated as 35, indicating obesity. A BMI of 27 falls within the overweight range, not obesity (which starts at 30). Choices A and B are incorrect because a BMI of 35 indicates obesity, not normal limits or being lower than normal. Therefore, the correct answer is C, indicating obesity based on the BMI calculation.

5. In hanging a parenteral IV fluid that is to be infused by gravity, rather than with an infusion pump, the nurse notes that the IV tubing is available in different drop factors. Which tubing is a microdrop set?

• A. 15 drops per milliliter
• B. 60 drops per milliliter
• C. 20 drops per milliliter
• D. 10 drops per milliliter

Correct answer: B

Rationale: A microdrop set delivers 60 drops per milliliter of IV fluid. This allows for a more precise control of the infusion rate. The correct choice is B because it provides the desired microdrop rate. Choices A, C, and D are incorrect. A delivers 15 drops per milliliter, which is a macrodrop set. C delivers 20 drops per milliliter, also a macrodrop set. D delivers 10 drops per milliliter, another macrodrop set. Therefore, the correct choice for a microdrop set is B.
