Correct Answer: C

Rationale: Ineffective breathing pattern is the highest priority nursing problem for a client with Guillain-Barre syndrome due to the potential risk of respiratory failure. As the paralysis ascends, it can affect the muscles needed for breathing, leading to respiratory compromise. Addressing this problem promptly is crucial to prevent respiratory distress and failure. Choices A, B, and D are also important nursing problems in Guillain-Barre syndrome, but ensuring effective breathing takes precedence over coping, nutrition, and mobility due to the immediate threat it poses to the client's life.

Correct Answer: A

Rationale: The correct answer is to observe the PICC line site for inflammation. When a client with a PICC line develops a fever, it could indicate an infection related to the catheter. Assessing the PICC line site for signs of inflammation, such as redness, warmth, swelling, or drainage, is crucial in identifying a potential infection early. Choice B is incorrect because increasing fluid intake is not directly related to assessing a PICC line for infection. Choice C is not the most appropriate assessment in this situation as monitoring blood pressure may not directly help in identifying the cause of the fever. Choice D is unrelated to the assessment of a fever in a client with a PICC line.

Correct Answer: B

Rationale: The best response in this situation is to offer a distraction to the child. Reading a book can help soothe the child during separation from the parent by redirecting their attention. Choice A might not be as effective as providing a distraction like reading a book. Choice C dismisses the child's feelings and generalizes behavior, which is not helpful. Choice D diminishes the child's emotions and does not provide a constructive way to help the child cope with the separation anxiety.

Correct Answer: D

Rationale: The correct answer is D. A sudden absence of pain in a client with severe abdominal pain may indicate a serious condition such as internal bleeding. This sudden change in pain status requires immediate assessment to rule out any life-threatening complications. Choices A, B, and C do not indicate an acute change in the client's condition that would necessitate immediate attention compared to sudden pain relief in a client with severe abdominal pain.

Correct Answer: C

Rationale: The correct action for the nurse to take when a pregnant woman is choking and unable to speak is to perform the Heimlich maneuver using subdiaphragmatic thrusts. This technique is recommended for a pregnant woman to prevent harm to the fetus. Option A, cardiopulmonary resuscitation with uterine tilt, is not indicated for a choking episode. Option B, the Heimlich maneuver using chest thrusts, can potentially harm the gravid uterus. Option D, calling 911 immediately before providing assistance, can lead to a delay in addressing the immediate choking emergency.
