Correct Answer: B

Rationale: The correct answer is B: Positioning the patient on his or her side. This is essential for a lumbar puncture as it helps to open up the spinal spaces, making it easier and safer for the procedure. Positioning the patient on their side also helps prevent complications such as nerve damage or spinal fluid leakage. A: Administering enemas until clear is unnecessary and not directly related to preparing a patient for a lumbar puncture. C: Removing all metal jewelry is important to prevent interference with imaging studies, but it is not directly related to preparing for a lumbar puncture. D: Removing the patient’s dentures is not specifically required for a lumbar puncture procedure.

Correct Answer: C

Rationale: Rationale: - Paraplegia refers to paralysis of the lower extremities. - The prefix "para-" means alongside or beside, indicating lower body involvement. - Option A is incorrect as it refers to quadriplegia. - Option B is incorrect as it refers to quadriplegia. - Option D is incorrect as it refers to hemiplegia.

Correct Answer: A

Rationale: The correct answer is A. Standard precautions include wearing gloves when there is a potential for contact with blood or body fluids. Emptying a bedpan involves contact with bodily fluids, thus gloves are necessary to prevent exposure to pathogens. Choice B is incorrect because wearing a gown and protective eyewear is not necessary for obtaining a urine specimen via catheterization unless there is a risk of splashing or spraying of fluids. Choice C is incorrect as needles should always be disposed of in a proper sharps container with the cap secured to prevent accidental needlestick injuries. Choice D is incorrect because applying eyedrops does not involve contact with blood or body fluids, so wearing gloves is not necessary according to standard precautions.

Correct Answer: A

Rationale: The correct answer is A: Physiologic. Impaired Gas Exchange pertains to the basic physiological need for oxygenation, which is fundamental for survival. Maslow's hierarchy states that physiological needs are the most fundamental and must be met before progressing to higher-level needs. Safety, love and belonging, and self-actualization are higher-level needs compared to physiological needs. Therefore, Impaired Gas Exchange aligns with the physiological level of needs in Maslow's hierarchy.

Correct Answer: C

Rationale: The correct answer is C: Myotic. Myotic eyedrops constrict the pupil, allowing aqueous humor to flow around the lens. Myotic agents, such as pilocarpine, work by stimulating the sphincter muscle of the iris. Osmotic eyedrops (A) reduce intraocular pressure, mydriatic eyedrops (B) dilate the pupil, and cycloplegic eyedrops (D) paralyze the ciliary muscle to prevent accommodation.
