1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?

Correct answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

2. A healthcare professional working in the emergency department is witnessing the signing of informed consent forms for the treatment of multiple clients during their shift. Which of the following signatures may the healthcare professional legally witness?

Correct answer: A

Rationale: The correct answer is A. A 16-year-old who is married can legally sign an informed consent form. In this case, being married at 16 may indicate legal emancipation or the ability to consent to medical treatment. Choice B is incorrect because having schizophrenia doesn't automatically imply incapacity to provide informed consent. Choice C is incorrect as an adoptive parent does not have the legal authority to provide consent for medical treatment on behalf of a child without proper documentation. Choice D is incorrect as a 17-year-old mother would generally not have the legal capacity to give consent for her toddler, as parental consent is usually required for minors.

3. The nurse is providing care for a client with a wound infection. Which type of precautions should the nurse implement?

Correct answer: C

Rationale: Contact precautions are necessary when caring for a client with a wound infection to prevent the spread of infection. Contact precautions involve practices such as wearing gloves and gowns, and ensuring proper hand hygiene. Airborne precautions are for diseases transmitted by small droplet nuclei that can remain suspended in the air, like tuberculosis. Droplet precautions are for diseases transmitted through respiratory droplets larger than 5 microns, such as influenza. Standard precautions are used for all clients to prevent the spread of infection and include practices like hand hygiene, use of personal protective equipment, and safe injection practices. In this case, since the client has a wound infection, the nurse should focus on implementing contact precautions to reduce the risk of spreading the infection to themselves or others.

4. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

Correct answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.

5. A healthcare provider is assessing a client's ability to balance. Which of the following actions is appropriate when the healthcare provider conducts a Romberg test?

Correct answer: C

Rationale: The Romberg test is a neurological test that assesses proprioception and balance. To perform this test, the client is asked to stand with their feet together and arms at their sides while closing their eyes. By removing visual input, the test challenges the vestibular and proprioceptive systems. Choices A, B, and D are incorrect because they do not align with the proper procedure for conducting the Romberg test. Extending arms in front, walking heel to toe, or placing hands on hips are not part of the Romberg test protocol and may introduce variables that could affect the assessment of balance.
