Correct Answer: D

Rationale: Encouraging clients with paranoia to express their concerns and validating their feelings is crucial as it helps establish trust and reduce anxiety. This approach also aids in building a therapeutic relationship. Reassuring the client that their fears are unfounded (Choice A) may invalidate their feelings and worsen trust. Placing the client in a private room to reduce stimuli (Choice B) may be helpful in some situations but does not address the underlying issue of paranoia. Providing a distraction (Choice C) may temporarily shift the client's focus but does not address the root cause of the paranoia. Therefore, the priority intervention is to encourage the client to express their concerns and validate their feelings.

Correct Answer: C

Rationale: The correct answer is C. Daily use of spironolactone for hypertension can increase the risk of hyperkalemia and interact with penicillin, leading to adverse reactions. Choice A is incorrect because the sputum culture showing Streptococcus pneumoniae is an expected finding in a patient with pneumonia and does not increase the risk of an adverse reaction to penicillin. Choice B is incorrect as previous treatment with penicillin does not necessarily increase the risk of an adverse reaction to penicillin if there was no history of allergic reactions. Choice D is also incorrect as a documented allergy to sulfa drugs does not directly increase the risk of an adverse reaction to penicillin.

Correct Answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

Correct Answer: B

Rationale: The correct intervention to help manage the client's pain in acute pancreatitis is to place the client in a side-lying position with knees bent. This position can alleviate abdominal pain by reducing pressure on the pancreas and improving comfort. Encouraging deep breathing exercises (Choice A) is beneficial for other conditions but may not directly help alleviate abdominal pain in pancreatitis. Administering oral analgesics (Choice C) may be necessary but is not the initial priority for managing pain in acute pancreatitis. Encouraging the client to take small sips of water (Choice D) is important for hydration but is not directly related to pain management in this context.

Correct Answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are more susceptible to lead poisoning from environmental sources due to their behaviors like hand-to-mouth contact and exploratory behaviors. Choices A, C, and D are less likely to be at high risk for lead poisoning compared to young children due to differences in exposure levels and behaviors related to potential sources of lead contamination.
