NURS 5315 Final Questions and Verified Answers, 100% Score Guarantee Pass (Latest 2025) A patient in respiratory distress and is breathing 33 breaths per minute. Which ABG value is consistent with the clinical scenario?
PCO2 15
pH 7.30 pH 7.45 O2 sat 100% - Correct Answers ✅A patient who is breathing 33 breaths per minute is hyperventilating and blowing off CO2; therefore the PCO2 level will be low. The patient will most likely experience a respiratory alkalosis and the two pH values provided are not consistent with this diagnosis.A patient has a sodium level of 115 mEq/L and is disoriented and lethargic. Which pathological process best explains this patient's symptoms?
- The action potential has become hyperpolarized.
- Water has shifted into the neurons and caused them to
- Water has shifted into the vascular space and dehydrated
- The action potential has become hypopolarized. - Correct
swell.
the neurons.
Answers ✅b. The cause of neurologic symptoms associated with a sodium imbalance is directly related to fluid shifting into or out of the neurons of the brain. With a serum sodium of 115 mEq/L, water shifts into the neurons and causes them 1 / 4

Hypernatremia causes water to shift out of the cell into the intravascular space and causes the neurons to become dehydrated. An alteration in the action potential is not seen with sodium imbalances.A patient experiencing dehydration should be monitored for which electrolyte imbalance?
- Hyperkalemia
- Hypocalcemia
- Hypercalcemia
- Hyponatermia - Correct Answers ✅a. Serum osmolality
is increased during times of dehydration. An elevated serum osmolality will pull potassium into the intravascular space from the intracellular space and cause a rise in serum potassium.A married couple presents to your office for genetic counseling. The husband has an autosomal recessive disease and his wife has a heterozygous genotype for the disease.They ask you, What is the chance that our baby will have the disease? Which of the following answers is correct?25% 50%

NURS 5315 Final Questions and Verified Answers, 100% Score Guarantee Pass (Latest 2025) 100% - Correct Answers ✅A chromosome is a package of material located inside the cell nucleus which is made of proteins and a single molecule of DNA. There are 23 pairs of chromosomes in each human cell for a total of 46 chromosomes. Chromosomes are separated into two identical sets during mitosis or meiosis. This provides a set of chromosomes to each daughter cell which results from cell division. This process is responsible for the transfer of genetic information to the daughter cells. The first 22 pairs of chromosomes are known as autosomes. The 23rd pair of chromosomes is the pair which contains the genetic information for gender. This pair contains the genetic information which delineates between the male and female genders. Females have two X chromosomes (XX) and males have an XY chromosome pair. Autosomal chromosomes are said to be autologous. This means they do not carry genetic information pertaining to gender. Autosomal genetic diseases are carried on the first 22 pairs of chromosomes. Sex-linked diseases are only carried on the 23rd pair of chromosomes.The autosomal chromosomes are nearly identical to one another and are considered homologous to one another. Each autosomal chromosome in a pair carries identical genes.These two genes are known as alleles. The alleles occupy the same site on each partner of the chromosome pair and code for the same genetic trait or physiologic function. Alleles can be dominant or recessive. One allele may be dominant and the other recessive, or they both may be dominant or both recessive. The dominant alleles' genetic code will always manifest in the individual's phenotype. The information in the recessive allele is typically not expressed in the phenotype 3 / 4

For the purpose of clarity in use, the dominant gene is assigned a capital letter and the recessive gene is a A child is diagnosed with hemophilia. This is an example of which genetic concept?Phenotype Genotype Autosomal transmission of the disease Transcription - Correct Answers ✅The expression of a genetic disease is an example of a phenotype. A genotype is a gene's programming. Hemophilia is transmitted on the x- chromosome and is not transmitted via the autosomes. This is not an example of transcription.Dehydration triggers which physiologic response?Increased secretion of renin.Increase secretion of natriuretic peptides.Decreased secretion of antidiuretic hormone.Decreased serum osmolality. - Correct Answers ✅Dehydration will trigger the release of renin when renal perfusion is impaired. The other answers are seen during times of fluid volume overload.
