Health Promotion and Maintenance NCLEX PN Questions Questions

Extract:


Question 1 of 5

Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:

Correct Answer: A

Rationale: Levothyroxine is safe and effective with virtually no side effects when dosed properly. A single, daily dose is possible because of the long half-life (7 days). Levothyroxine tablets are available in a wide range of concentrations to meet individual client requirements. Levothyroxine (T4) is a prodrug of T3.

Question 2 of 5

What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?

Correct Answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation.
Choice A is incorrect because concentrations above 20% are too high for a peripheral IV.
Choice B is incorrect as dextrose concentrations below 5% are too low to be effective.
Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.

Question 3 of 5

A healthcare professional reviewing the health care record of a client notes documentation of grade 4 muscle strength. The healthcare professional understands that this indicates:

Correct Answer: D

Rationale: Muscle strength is graded on a scale of 0 to 5. A grade of 5 indicates normal strength and is described as full ROM against gravity with full resistance. Grade 4 indicates good strength and full ROM against gravity with some resistance. Grade 3 indicates fair strength and full ROM with gravity. Grade 2 indicates poor strength and full ROM with gravity eliminated (passive motion). Grade 1 indicates trace strength and slight contraction. Grade 0 indicates zero strength and no contraction.
Therefore, the correct answer is 'Full ROM against gravity with some resistance.'

Choices A, B, and C are incorrect as they do not match the description of muscle strength associated with a grade of 4.

Question 4 of 5

When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?

Correct Answer: C

Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope.
Therefore, the correct answer is the optic disc.

Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.

Question 5 of 5

You are caring for a 78-year-old woman who is wondering why she was diagnosed with glaucoma. Although she has several risk factors, which of these is not one of them?

Correct Answer: D

Rationale: Age over 60 and Mexican-American heritage are recognized as risk factors for glaucoma. Elevated blood pressure is also a risk factor due to its potential to cause optic nerve damage. While 20/80 vision indicates poor eyesight, it is not a direct causal factor for glaucoma. Glaucoma is mainly associated with factors like age, ethnicity, and certain medical conditions, rather than a specific visual acuity measurement.
Therefore, 20/80 vision is not a risk factor for glaucoma, making it the correct answer. The other choices, such as age, Mexican-American heritage, and elevated blood pressure, are established risk factors for developing glaucoma, as they are associated with an increased likelihood of the condition.
