Nursing Elites

1. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

2. Integrated management for childhood illness is the universal protocol of care endorsed by WHO and is used by different countries worldwide, including the Philippines. In any case that the nurse classifies the child and categorizes the signs and symptoms in the PINK category, you know that this means:

• A. Urgent referral
• B. Antibiotic Management
• C. Home treatment
• D. Outpatient treatment facility is needed

Correct answer: B

Rationale: When a child is classified under the PINK category in the Integrated Management of Childhood Illness (IMCI) guidelines, it signifies the need for antibiotic management. This category indicates severe signs and symptoms requiring immediate antibiotic treatment to address the underlying infection. Choices A, C, and D are incorrect because the PINK category specifically calls for urgent antibiotic management rather than urgent referral, home treatment, or outpatient treatment facility.

3. Which of the following gauges should you prepare for spinal anesthesia if the anesthesiologist requires a pink spinal set and a blue spinal set as backup?

• A. Gauges 16 and 22
• B. Gauges 18 and 16
• C. Gauges 16 and 20
• D. Gauges 25 and 22

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. Which food item interferes with the effectiveness of warfarin?

• A. Cauliflower
• B. Zucchini
• C. Green beans
• D. Broccoli

Correct answer: D

Rationale: Broccoli is high in vitamin K, which can affect the effectiveness of warfarin. Warfarin is an anticoagulant medication that functions by reducing the activity of vitamin K in the body. When one consumes broccoli, which is rich in vitamin K, it could counteract the anticoagulant effect of warfarin, thereby interfering with its effectiveness. On the other hand, cauliflower, zucchini, and green beans do not have significant levels of vitamin K and hence, are not known to impact the effectiveness of warfarin.

5. Which of the following statements about Z-Track technique is false?

• A. Z-Track injections prevent irritation of the subcutaneous tissues
• B. The technique involves creating a Zig-Zag like pattern of medication
• C. It forces the medication to be contained in the subcutaneous tissues
• D. It is used when administering Parenteral Iron

Correct answer: B

Rationale: The Z-Track technique is aimed at preventing medication leakage into the surrounding tissues by sealing the medication in the muscle, not by creating a Zig-Zag pattern. Choice A is correct as Z-Track injections help prevent irritation. Choice C is correct as it accurately describes how the technique works. Choice D is also correct as the Z-Track technique is commonly used when administering Parenteral Iron to prevent staining and irritation of the surrounding tissues.
