NURS 172 Exam 3 practice questions with
correct answers
The |nurse |correlates |increased |circulating |levels |of |triiodothyronine |and |thyroxine |to |which
|physiological |response?
1. |Decreased |secretion |of |thyrotropin-releasing |hormone |(TRH)
2. |Decreased |secretion |of |thyrocalcitonin
3. |Increased |secretion |of |thyroid-stimulating |hormone |(TSH) |
4. |Increased |secretion |of |parathyroid |hormone |- |CORRECT |ANSWER✔✔-1: |
1. |As |levels |of |circulating |T3 |and |T4 |increase, |the |feedback |to |the |hypothalamus |is |to |decrease
|secretion |of |thyrotropin-releasing |hormone |(TRH).
2. |Thyrocalcitonin |(calcitonin) |has |a |role |in |the |regulation |of |calcium |and |is |not |affected |by
|circulating |levels |of |T3 |and |T4.
3. |As |levels |of |circulating |T3 |and |T4 |increase, |the |feedback |to |the |hypothalamus |is |to |decrease
|secretion |of |TRH. |As |TRH |secretion |decreases, |thyroid-stimulating |hormone |(TSH) |secretion
|also |decreases.
4. |Parathyroid |hormone |secretion |is |not |affected |by |circulating |levels |of |T3 |and |T4.
The |nurse |is |preparing |a |teaching |tool |that |focuses |on |the |endocrine |system. |How |should |the
|nurse |explain |the |negative |feedback |system?
1. |Hormone |secretion |increases |when |circulating |levels |drop.
2. |Hormone |secretion |increases |when |target |organs |send |signals.
3. |Hormone |secretion |increases |when |circulating |levels |increase.
4. |Hormone |secretion |increases |when |the |target |tissue |does |not |recognize |the |level. |-
CORRECT |ANSWER✔✔-1: |
|
1. |Hormonal |release |is |controlled |by |a |negative |feedback |system |that |increases |hormone
|secretion |when |circulating |levels |are |decreased.
,2. |Increasing |hormone |secretion |when |the |target |organ |sends |signals |does |not |describe |a
|negative |feedback |system.
3. |Increasing |secretion |when |the |circulating |levels |increase |describes |a |positive |feedback
|system.
4. |Increasing |secretion |when |the |target |tissue |does |not |recognize |the |level |does |not |describe
|a |negative |feedback |system.
Which |assessment |data |from |a |patient |who |has |been |on |long-term |steroid |therapy |requires
|an |immediate |intervention?
1. |Insomnia
2. |Truncal |obesity
3. |Decreased |blood |glucose |
4. |Preexisting |hypertension |- |CORRECT |ANSWER✔✔-3: |
1. |Insomnia |is |an |expected |side |effect |for |long-term |steroid |therapy. |
2. |Truncal |obesity |is |an |expected |side |effect |for |long-term |steroid |therapy.
3. |Patients |who |are |prescribed |corticosteroids |for |more |than |10 |to |14 |days |require |"tapering"
|of |the |medication. |Because |of |the |effects |of |the |exogenous |corticosteroid |on |the
|hypothalamus, |anterior |pituitary, |and |adrenal |cortex, |the |normal |hormonal |feedback |system |is
|interrupted. |Abrupt |withdrawal |of |the |exogenous |medication |may |lead |to |adrenal
|insufficiency, |which |is |a |medical |emergency |characterized |by |decreased |blood |pressure |and
|hypoglycemia. |A |decreased |blood |glucose |requires |the |nurse |to |collect |additional |data.
4. |Preexisting |hypertension |is |not |data |that |necessitates |additional |data |collection |based |on
|the |patient's |long-term |steroid |therapy |status.
A |patient |is |diagnosed |with |a |disorder |of |the |hypothalamus. |To |which |other |gland |is |this
|structure |attached?
1. |Thyroid
2. |Thalamus
3. |Pituitary |gland |
,4. |Adrenal |glands |- |CORRECT |ANSWER✔✔-3: |
1. |The |thyroid |gland |is |in |the |neck.
2. |The |hypothalamus |is |a |small |structure |located |beneath |the |thalamus.
3. |The |hypothalamus |is |connected |to |the |pituitary |gland |by |the |infundibulum.
4. |The |adrenal |glands |sit |atop |the |kidneys.
The |nurse |monitors |for |which |clinical |manifestation |in |the |patient |with |a |decrease |in
|antidiuretic |hormone |(ADH) |secretion?
1. |Increased |sodium |excretion
2. |Increased |potassium |excretion
3. |Increased |urine |output
4. |Increased |urine |specific |gravity |- |CORRECT |ANSWER✔✔-3: |
1. |Antidiuretic |hormone |(ADH) |does |not |impact |sodium |reabsorption |or |excretion. |ADH
|controls |water |reabsorption |in |the |kidneys.
2. |Antidiuretic |hormone |does |not |impact |potassium |reabsorption |or |excretion. |ADH |controls
|water |reabsorption |in |the |kidneys.
3. |Antidiuretic |hormone |is |secreted |from |the |posterior |pituitary |gland |in |response |to
|decreased |blood |pressure, |dehydration, |and |increased |serum |osmolality |and |works |by
|increasing |water |reabsorption |in |the |kidneys. |Decreased |ADH |results |in |increased |output |of
|dilute |urine.
4. |A |lack |of |ADH |results |in |excretion |of |large |amounts |of |dilute |urine |with |a |low |specific
|gravity.
On |physical |examination, |the |nurse |notes |increased |pigmentation |and |correlates |this |to |a
|dysfunction |in |which |endocrine |gland?

3. |Anterior |pituitary |
, 4. |Adrenal |cortex |- |CORRECT |ANSWER✔✔-3: |
1. |The |thyroid |gland |does |not |impact |hair |and |skin |color. |Melanocyte-stimulating |hormone
|from |the |anterior |pituitary |gland |affects |skin |and |hair |color.
2. |The |posterior |pituitary |gland |does |not |impact |hair |and |skin |color. |Melanocyte-stimulating
|hormone |from |the |anterior |pituitary |gland |affects |skin |and |hair |color.
3. |Melanocyte-stimulating |hormone |is |secreted |from |the |anterior |pituitary |gland |and |affects
|skin |and |hair |color.
4. |The |adrenal |glands |do |not |impact |hair |and |skin |color. |Melanocyte-stimulating |hormone
|from |the |anterior |pituitary |gland |affects |skin |and |hair |color.
In |assessing |a |patient |with |increased |aldosterone, |the |nurse |recognizes |which |actions |of |this
|hormone?
1. |Increases |potassium |sodium |reabsorption |in |the |kidneys
2. |Increases |sodium |reabsorption
3. |Decreases |calcium |reabsorption |in |the |kidneys |
4. |Decreases |glucose |reabsorption |in |the |kidneys |- |CORRECT |ANSWER✔✔-2: |
1. |Aldosterone |stimulation |leads |to |excretion |of |potassium.
2. |Aldosterone |stimulation |leads |to |reabsorption |of |sodium |and |water |and |excretion |of
|potassium.
3. |Aldosterone |has |no |effect |on |calcium |regulation.
4. |Aldosterone |has |no |effect |on |glucose |regulation.
In |caring |for |a |patient |taking |medications |to |suppress |the |immune |response, |it |is |important
|that |the |nurse |recognize |that |these |medications |can |produce |which |effect?
1. |Increased |secretion |of |cortisol
2. |Increased |secretion |of |adrenocorticotropic |hormone |(ACTH)
3. |Decreased |secretion |of |corticotropin-releasing |hormone |4. |Decreased |secretion |of
antidiuretic |hormone |- |CORRECT |ANSWER✔✔-3: |
