1. 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.

2. Which of the following foods is the best source of omega-3 fatty acids?

• A. Salmon
• B. Chicken
• C. Spinach
• D. Eggs

Correct answer: A

Rationale: Salmon is the correct answer as it is a rich source of omega-3 fatty acids, specifically EPA and DHA, which are known to be beneficial for heart health. Chicken, spinach, and eggs do not contain significant levels of omega-3 fatty acids compared to salmon. While eggs do contain some omega-3s, the amount is considerably lower than what is found in fatty fish like salmon.

3. A client with hypertension is being educated by a nurse about a heart-healthy diet. Which of the following statements indicates that the client understands the teaching?

• A. I will get 15% of my total daily calories from saturated fats.
• B. I will decrease the potassium in my diet.
• C. I will limit my daily sodium intake to 3 grams.
• D. I will eat five 8-ounce servings of fruit daily.

Correct answer: C

Rationale: The correct answer is C. Limiting daily sodium intake to 3 grams is crucial in managing blood pressure and is a fundamental aspect of a heart-healthy diet. High sodium intake can contribute to hypertension and cardiovascular issues. Choices A, B, and D are incorrect because getting 15% of daily calories from saturated fats, decreasing potassium intake, and eating five servings of fruit do not directly address the management of hypertension through sodium restriction.

4. How long can Vitamin A be stored in the liver for at least?

• A. 1 month.
• B. 6 months.
• C. 1 year.
• D. 18 months.

Correct answer: C

Rationale: Vitamin A can be stored in the liver to meet basic needs for at least 1 year. This storage capacity allows the body to have a reserve of Vitamin A to sustain its needs over an extended period. Choices A, B, and D are incorrect because they underestimate the storage capacity of Vitamin A in the liver, which can last longer than these durations.

5. During an initial visit with an older adult client living alone and having difficulty preparing meals, what should the home health nurse do first?

• A. Discuss nutritional requirements with the client.
• B. Refer the client to a senior citizen center.
• C. Arrange for a home-delivered meal program.
• D. Perform a nutrition screening.

Correct answer: D

Rationale: Performing a nutrition screening is the most appropriate action for the nurse to take first. This allows the nurse to assess the client's current nutritional status and identify any specific needs. Discussing nutritional requirements with the client (Choice A) may be important but should come after the initial assessment. Referring the client to a senior citizen center (Choice B) or arranging for a home-delivered meal program (Choice C) are actions that may be considered later based on the findings of the nutrition screening.
