Correct Answer: A

Rationale: When assessing breath sounds in a client with pneumonia, the nurse should follow a systematic pattern from side-to-side moving down the client's chest. This approach ensures a comprehensive evaluation of breath sounds across different lung fields. Asking the client to breathe in deeply through their nose (Choice B) is not necessary for assessing breath sounds. Instructing the client to sit upright with their head slightly tilted backward (Choice C) is not directly related to assessing breath sounds and may not be required. Placing the diaphragm of the stethoscope on the client's chest (Choice D) is not the correct technique for auscultating breath sounds, as the diaphragm should be used for this purpose.

Correct Answer: A

Rationale: Assigning an admission with atrial fibrillation and heart failure to a PN is not appropriate. This complex case requires more advanced skills and should not be managed by a PN without adequate support. The PN may not have the necessary training or expertise to handle such a critical situation effectively. Choice B is a suitable assignment for a PN nursing student as they can handle a client who had a major stroke 6 days ago. Choice C is also appropriate as a child with burns receiving packed cells and albumin IV running can be managed by the charge nurse. Choice D is within the scope of practice for a UAP since an elderly client post-myocardial infarction a week ago may require basic care and assistance.

Correct Answer: C

Rationale: The correct answer is C: 'Do not discontinue the medication abruptly.' It is crucial for clients prescribed prednisone to not stop the medication suddenly to prevent adrenal insufficiency, as this medication suppresses the body's natural production of cortisol. Choice A is incorrect because prednisone should be taken with food to minimize gastrointestinal side effects, not necessarily to prevent stomach upset. Choice B is incorrect as there is no specific need to avoid sunlight while taking prednisone. Choice D is not directly related to prednisone use; while adequate fluid intake is generally beneficial, it is not a specific instruction for prednisone administration.

Correct Answer: C

Rationale: During puberty in males, the first physical change that typically occurs is the enlargement of the testes and scrotum. This change is due to increased production of testosterone, which stimulates growth and development of the genital organs. The appearance of downy hair on the upper lip (Choice A) and hair growth in the axillae (Choice B) usually follow the enlargement of the testes and scrotum. Deepening of the voice (Choice D) is a later stage change that occurs during puberty as the larynx (voice box) grows and the vocal cords lengthen and thicken.

Correct Answer: C

Rationale: During a thoracic examination, normal findings should include resonance, which is the expected sound when percussing the thorax. Resonance indicates healthy lung tissue and air-filled spaces. Abnormal findings such as rhonchi and crackles suggest issues like lung congestion or inflammation. Tactile fremitus refers to vibrations felt on the chest wall during palpation and is not typically assessed during percussion and auscultation of the thorax.
