The strength ratio of the lidocaine:ointment is 1:13.33.
To find the percentage strength of the lidocaine ointment, we need to calculate the amount of lidocaine in grams relative to the total weight of the ointment.
Since the ointment contains 75 mg of lidocaine per gram, we can say that it has a concentration of 75 mg/g.
To convert this concentration to a percentage, we divide it by 10 since 1 gram is equal to 10 decigrams (dgs). Therefore:
75 mg/g ÷ 10 = 7.5%
So, the lidocaine ointment has a percentage strength of 7.5%.
Regarding the strength ratio, we compare the amount of lidocaine to the total weight of the ointment. In this case, the ratio is:
75 mg/g : 1000 mg/g
Simplifying, we get:
75 : 1000
Dividing both sides by 75, we find: 1 : 13.33

A researcher wishes to estimate the number of households with two tablets. What size sample should be obtained in order to be 95% confident that the sample proportion will not differ from the true proportion by more than 6%? A previous study indicates that the proportion of households with two tablets is 20%. Round up to the nearest whole number.
Answer: To determine the sample size needed, we can use the formula for sample size estimation for proportions. The formula is given by:
n = (Z^2 * p * (1-p)) / E^2
Where:
n = sample size
Z = Z-value corresponding to the desired level of confidence (in this case, 95% confidence level)
p = estimated proportion (from the previous study)
E = maximum allowable error (6% in this case)
Given:
Z = 1.96 (corresponding to a 95% confidence level)
p = 0.20 (proportion from the previous study)
E = 0.06 (maximum allowable error)
Substituting the values into the formula:
n = (1.96^2 * 0.20 * (1-0.20)) / 0.06^2
n = (3.8416 * 0.20 * 0.80) / 0.0036
n = 0.61472 / 0.0036
n = 170.2
Rounding up to the nearest whole number, the sample size needed is 171.
Explanation: :)
The researcher should obtain a sample size of 267 households to achieve the desired level of confidence and margin of error.
To estimate the number of households with two tablets with 95% confidence that the sample proportion will not differ from the true proportion by more than 6%, the researcher needs to obtain a sample size of at least 267 households. This can be calculated using the formula:
n = (z^2 * p * q) / E^2
where:
- z is the z-score corresponding to the desired confidence level (1.96 for 95%)
- p is the estimated proportion from the previous study (0.20)
- q is the complement of p (1 - 0.20 = 0.80)
- E is the maximum margin of error (0.06)
Plugging in these values, we get:
n = (1.96^2 * 0.20 * 0.80) / 0.06^2
n = 266.44
Rounding up to the nearest whole number, the researcher should obtain a sample size of 267 households to achieve the desired level of confidence and margin of error.

which type of hypersensitivity cannot be transferred with serum antibody
Type IV hypersensitivity, also known as delayed-type hypersensitivity (DTH), is the type of hypersensitivity that cannot be transferred with serum antibody.
Type IV hypersensitivity is mediated by T cells rather than antibodies. It involves a delayed immune response that typically occurs within 24 to 72 hours after exposure to an antigen. This type of hypersensitivity is associated with cell-mediated immune responses, such as the activation of T lymphocytes and the release of cytokines. Unlike the other types of hypersensitivity (Type I, Type II, and Type III), which involve the presence of circulating antibodies in the serum, Type IV hypersensitivity does not rely on serum antibodies for its transfer or manifestation.

Factors that influence the nutrition needs of young adults include
a. growth
b. climate
c. personality type
d. physical activity
Growth and physical activity are factors that influence the nutrition needs of young adults. The correct answer is option a. and d.
Young adults are still growing and developing, which means that their bodies require more nutrients than adults who have stopped growing. This makes growth a crucial factor in determining their nutrition needs. Additionally, physical activity plays a key role in determining the amount of nutrients that a young adult requires.
Those who are more physically active require more energy and nutrients to support their increased activity levels. On the other hand, climate and personality type are not significant factors in determining nutrition needs. While climate can affect the availability of certain foods, it does not directly impact an individual's nutritional requirements. Similarly, personality type does not influence nutrition needs. Overall, young adults should aim to maintain a balanced diet that meets their growth and activity needs.

What is the basic pathological change with macular degeneration?
a. Increased amount of aqueous humor in the eye
b. Movement of vitreous humor between the retina and the choroid
c. Degeneration of the retinal cells in the fovea centralis
d. Damage to the optic nerve and meninges
The basic pathological change with macular degeneration is degeneration of the retinal cells in the fovea centralis. The correct answer is option c.
Macular degeneration is an age-related eye disease that primarily affects the central part of the retina called the macula. It involves the degeneration of retinal cells in the fovea centralis, which is responsible for sharp central vision needed for activities like reading, driving, and recognizing faces.
This degeneration can occur in two forms - dry (atrophic) and wet (neovascular). Dry macular degeneration is characterized by the accumulation of drusen (yellow deposits) beneath the retina, while wet macular degeneration involves the growth of abnormal blood vessels beneath the macula. Both forms lead to the deterioration of central vision over time.

Therefore, the nurse should monitor the client closely for respiratory depression and other side effects of the medication and adjust the dosage accordingly. Additionally, the nurse should be aware of potential drug interactions with other medications the client may be taking for their myxedema.
When administering opioids to a client with myxedema who has undergone abdominal surgery, the nurse should consider that patients with myxedema may have an increased sensitivity to opioids due to their altered metabolism and reduced ability to clear the medication from their system.
