1. Which statement by the client with chronic obstructive lung disease indicates an understanding of the major reason for the use of occasional pursed-lip breathing?

A. ''This action of my lips helps to keep my airway open.''
B. ''I can expel more air when I pucker up my lips to breathe out.''
C. ''My mouth doesn't get as dry when I breathe with pursed lips.''
D. ''By prolonging breathing out with pursed lips, the smaller areas in my lungs don't collapse.''

Correct answer: D

Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.

2. Which of the following descriptions best describes the function of the thyroid gland?

A. The thyroid gland converts glucose into glycogen
B. The thyroid gland secretes cortisol during times of stress
C. The thyroid gland regulates body metabolism
D. The thyroid gland affects skin pigmentation

Correct answer: C

Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.

3. Which of the following is an example of physical abuse?

A. A slap to the person's hand
B. Threatening the person
C. Ignoring and isolating a person
D. Leaving a patient soiled for hours

Correct answer: A

Rationale: The correct answer is 'A slap to the person's hand.' Slapping, hitting, and punching are clear examples of physical abuse. Physical abuse involves actions that can cause physical harm or injury to a person. Choice B, 'Threatening the person,' falls under the category of emotional or psychological abuse, where threats can cause fear and emotional distress but do not involve physical harm. Choice C, 'Ignoring and isolating a person,' is a form of neglect or emotional abuse, not physical abuse. Choice D, 'Leaving a patient soiled for hours,' is an example of neglect or lack of proper care, which is also not classified as physical abuse.

4. When percussing over the lungs of a 4-year-old child, the nurse hears bilateral loud, long, and low tones. How should the nurse proceed?

A. Palpate over the area for increased pain and tenderness.
B. Ask the child to take shallow breaths and percuss over the area again.
C. Refer the child to a specialist because of an increased amount of air in the lungs.
D. Consider this finding as normal for a child this age and proceed with the examination.

Correct answer: D

Rationale: In pediatric patients, loud, long, and low tones heard when percussing over the lungs are normal findings. These percussion notes are characteristic of a child's lung due to its thin chest wall and increased air content. It is unnecessary to palpate for pain and tenderness, ask the child to take shallow breaths and repeat the percussion, or refer the child to a specialist. Therefore, the correct action is to consider these findings as normal for the child's age and continue with the examination.

5. When performing CPR, at what rate should chest compressions be applied?

A. 100 per minute
B. 60 per minute
C. As quickly as possible
D. 200 per minute

Correct answer: A

Rationale: During CPR, chest compressions should be applied at a rate of 100 compressions per minute in order to effectively circulate blood and oxygen to vital organs. Option A, '100 per minute,' is the correct answer as it aligns with the recommended compression rate in CPR guidelines. Option B, '60 per minute,' is incorrect as it is too slow and may not provide adequate circulation. Option C, 'As quickly as possible,' is vague and does not specify the recommended compression rate. Option D, '200 per minute,' is incorrect as it exceeds the recommended rate and may not be as effective in maintaining perfusion.
